Interface Commands
This chapter is a reference for each of the interface commands.
admin-group
Use this command to create an administrative group to be used for links. Each link can be a member of one or more, or no administrative groups.
When used in the interface mode, this command adds a link between an interface and a group. The name is the name of the group previously configured. There can be multiple groups per interface. The group is created in configure mode, then interfaces are added to the group in interface mode.
Use the no parameter with this command to disable this command.

debounce-time
Use this command to set the debounce time for a interface.
The debounce timer avoids frequent updates (churn) to higher layer protocol during interface flapping. If the status of a link changes quickly from up to down and then back to up, the port debounce timer suppresses the link status notification. If the link transitions from up to down, but does not come back up, the port debounce timer delays the link status notification.
Note: Keep the following in mind when using the debounce timer:
• Debounce is not applicable for admin down operations.
• Debounce timer is supported only for physical L2 and L3 interfaces.
• The debounce flap-count refers to the number of flaps OcNOS receives while the debounce timer is running:
• The flap-count is only updated if the timer is still running and OcNOS receives a link status event for the interface.
• The flap-count is reset at the subsequent start of the debounce timer.
• Protocol-specific timers such as BFD which depend on the link status should be configured to a minimum of 1.5 times the value of the debounce timer. Otherwise it could affect the protocol states if the debounce timer is still running.
Use the no form of this command to turn-off the debounce timer on a interface.
Command Syntax
debounce-time <250-5000>
no debounce-time
Parameters
<250-5000>
Timer value in milliseconds.
Default
By default, disabled.
Command Mode
Interface mode

(config)#interface eth1
(config-if)#debounce-time 4000
delay-measurement dynamic twamp
This command will start the measurement on the interface by using the "interfaces" profile.
The user should be aware that the IP used as a reflector IP must be a directly connected IP.
In case hostname needs to be used, the user must be sure about the hostnames configured in the network.
In case the user configures the delay-measurement with a certain hostname and then the hostname entry in the DNS changes, the delay-measurement must be unconfigured and configured again for the new configuration to take effect (a clear command would not be sufficient in this situation)
Use the no form of this command to stop the delay measurement.

flowcontrol
Use this command to enable or disable flow control.
Flow control enables connected Ethernet ports to control traffic rates during periods of congestion by allowing congested nodes to pause link operations at the other end. If one port experiences congestion and cannot receive any more traffic, it notifies the other port to stop sending until the condition clears. When a local device detects congestion at its end, it notifies the remote device by sending a pause frame. On receiving a pause frame, the remote device stops sending data packets, which prevents loss of data packets during the period of congestion.
Use the no parameter with this command to disable flow control.
Command Syntax
flowcontrol both
flowcontrol send on
flowcontrol send off
flowcontrol receive on
flowcontrol receive off
no flowcontrol
Parameters
both
Specify flow control mode for sending or receiving.
send
Specify flow control mode for sending.
receive
Specify the flow control mode for receiving.
off

Header
Each entry in this table has a code preceding it, indicating the source of the routing entry. For example, O indicates OSPF as the origin of the route and K indicates that the route has been learned from the kernel.
Table 22-65 shows these codes and modifiers.
Table 22-65 explain the fields in the command output.
Table 22-65: route codes and modifiers
Code | Meaning | Description |
|---|
K | kernel | Routes added through means other than by using the CLI; for example by using the operating system route command. Static routes added using kernel commands and static routes added using OcNOS commands are different. The kernel static routes are not redistributed when you give the redistribute static command in a protocol. However, the kernel static routes can be redistributed using the redistribute kernel command. |
C | connected | Routes directly connected to the local device that were not distributed via IGP. The device inherently knows of these networks, so there is no need to learn about these from another device. Connected routes are preferred over routes for the same network learned from other routing protocols. Routes for connected networks always exist in the kernel routing table but as an exception are not marked as kernel routes because OcNOS always calculates entries for these routes upon learning interface information from the kernel. |
S | static | Routes manually configured via CLI which are not updated dynamically by IGPs. |
The codes below are for routes received and dynamically learned via IGP neighbors. These networks are not directly connected to this device and were announced by some other device on the network. IGPs update these routes as the network topology changes. |
R | RIP | RIP routing process and enter Router mode. |
B | BGP | Route is from an Border Gateway Protocol. |
O | OSPF | Modifiers for OSPF: IA - OSPF inter area N1 - OSPF NSSA external type 1 N2 - OSPF NSSA external type 2 E1 - OSPF external type 1 E2 - OSPF external type 2 |
i | IS-IS | Modifiers for IS-IS: L1 - IS-IS level-1 L2 - IS-IS level-2 ia - IS-IS inter area |
Other modifiers: |
v | vrf leaked | The device has two or more VRFs configured and each has at least one interface bound to it. While each VRF will have its own routing table, the VRFs can learn each other’s routes. |
* | candidate default | Route has been added to the FIB. With equal cost paths to a destination, the router does per-packet or per-destination load sharing. An asterisk ("*") means that the route is being used at that instant for forwarding packets. If you run the same show ip route x.x.x.x command over and over, you might see the * moving between the route entries. |
> | selected route | When multiple routes are available for the same prefix, the best route. When multiple entries are available for the same prefix, OcNOS uses an internal route selection mechanism based on protocol administrative distance and metric values to choose the best route. OcNOS populates the FIB with the best route to each destination |
p | stale info | A route information that is marked stale due to graceful restart. |
After the codes, the header has default gateway information:
Gateway of last resort is 10.12.4.1 to network 0.0.0.0
The “gateway of last resort”, also called the default gateway, is a static route that routes IP address 0.0.0.0 (all destinations) through a single host (the gateway). The effect of setting a gateway is that if no routing table entry exists for a destination address, packets to that address will be forwarded to the gateway router.
Route Entry Fields
Table 22-66 explains the each route entry fields.
Table 22-66: route entry output details
Field | Description |
|---|
Codes and modifiers | As explained in Table 22-65. |
IP address | IP address of the remote network. |
Administrative distance and metric | The administrative distance determines how trustworthy this route is. If there is a similar route but with a smaller administrative distance, it is used instead, because it is more “trustworthy”. The smaller the administrative distance, the more trustworthy the route. Directly connected routes have an administrative distance of 0, which makes them the most trustworthy type of route.The metric varies from protocol to protocol, and for OSPF the metric is cost, which indicates the best quality path to use to forward packets. Other protocols, like RIP, use hop count as a metric. For neighboring routers, the metric value is 1. |
Next hop router IP address | This route is available through the next hop router located at this IP address. This identifies exactly where packets go when they match this route. |
Outgoing interface name | Interface used to get to the next-hop address for this route. |
Duration | Length of time that this route has been present in the routing table. This is also the length of time this route has existed without an update. If the route were removed and then re-added (if the cable was disconnected, for instance), this timer would begin again at 00:00:00. |

The codes and modifier at the start of each route entry are explained in
Table 22-65.
Routes in the FIB are marked with a *. When multiple routes are available for the same prefix, the best route is indicated with the > symbol. Unselected routes have neither the * nor the > symbol.
Route Database Entry Examples
This example shows 2 entries in the route database; one learned from the kernel and the other derived from interface information.
K * 10.30.0.0/24 is directly connected, eth0
C *> 10.30.0.0/24 is directly connected, eth0
• Both these routes are in the same network 10.30.0.0/24.
• The first route has originated from the kernel. The * indicates that it has been added to the FIB.
• The second route is derived from the IP address of local interface eth0. It is marked as a connected route. Since a connected route has the lowest administrative distance, it is the selected route.
S *> 10.10.34.0/24 [1/0] via 10.10.31.16, eth2
O 10.10.34.0/24 [110/31] via 10.10.31.16, eth2, 00:21:19
• The same prefix was learned from OSPF and from static route configuration.
• Static routes are preferred over OSPF routes, so the static route is selected and installed in the FIB.
Note: If the static route becomes unavailable, OcNOS automatically selects the OSPF route and installs it in the FIB.

shutdown
Use this command to shut down an interface.
Use the no form of this command to bring up an interface.
Command Syntax
shutdown
no shutdown
Parameters
None
Default
No default value is specified
Command Mode
Interface mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
The following example shows the use of the shutdown command to shut down the interface called eth3.
#configure terminal
(config)#interface eth3
(config-if)#shutdown
speed
Use this command to set the link speed of the interface.
Use the no parameter to set the speed to its default value.
On copper ports, auto-negotiation is enabled by default and force speed is not supported.
On fiber optic ports, auto-negotiation is disabled by default. Auto-negotiation is not supported on fiber optic medium/AOC for speeds 10g and beyond. IP Infusion Inc.does not recommend using auto speed on such transceivers. On DAC cables, both force and auto-negotiation are supported.
IP Infusion Inc. recommends configuring the same speed mode on both peers.
When an interface is configured with the speed auto option, the negotiated parameters are speed,
duplex,
flowcontrol, and
fec, each of which is configured separately. Please see the respective command for details.
Note: For 10g DAC/AOC, setting speed auto negotiates with a maximum of 1G.
Note: Interface speed setting is only supported on physical front-panel ports and not supported on Management interface eth0.
Note: Configuring or unconfiguring speed will reset FEC to auto mode.
Table 22-69 shows the IP Infusion Inc. recommendations regarding front-panel port speed and transceivers.
Table 22-69: Recommendatons
Suported/Recommended | Explanation |
|---|
Not Supported | When front panel port capability is less than the transceiver’s capability the behavior is undefined. |
Not Recommended | When the transceiver’s capability and front panel port capability is the same, reducing the speed is not recommended. |
Recommended | When the transceiver’s capability is less than the front panel port capability, the behavior is undefined and the link might even come up. So speed needs to be set to match the transceiver’s capability. |
Table 22-70 show examples with front-panel configurations:
Table 22-70: Front-panel configurations
Front Panel Port | Explanation |
|---|
Front Panel Port 100g | When 40g transceivers are used, make sure to use the command speed 40g. IP Infusion Inc. does not recommend using 40g on 100g speed transceivers. |
Front Panel Port 40g | 100g transceivers should not be used. |
Front Panel Port 25g | When 10g transceivers are used, make sure to use the port-group command to reduce the speed to 10g. IP Infusion Inc. does not recommend to use 10g on 25g speed transceivers. When using 1g transceivers, make sure to set the speed to 1g. Below 25g, port-speed can defer (10g or 1g) for ports under same port-group i.e. 1 port can have 1g & remaining 10g but 1 port 25g & remaining 10g not allowed. When "no speed" command is used at interface level it tries to set speed "25g" to one of the port of port-group while other may be at 10g or 1g speed which is not allowed. Use "no port-group" command in such case. |
Front Panel Port 10g | 25g transceivers should not be used. When using 1g transceivers, make sure to set the speed to 1g. |
Front Panel Port 1g | 10g/25g transceivers should not be used. |
