Bridge Commands
This chapter provides a description, syntax, and examples of the bridge commands. It includes the following commands:
bridge acquire
Use this command to enable a bridge to learn station location information for an instance. This helps in making forwarding decisions.
Use the no parameter with this command to disable learning.
Command Syntax
bridge <1-32> acquire
no bridge <1-32> acquire
Parameter
<1-32>
Specify the bridge group ID.
Default
By default, learning is enabled for all instances.
Command Mode
Configure mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#configure terminal
(config)#bridge 3 acquire
(config)#no bridge 3 acquire
bridge address
Use this command to add a static forwarding table entry for the bridge.
Use the no parameter with this command to remove the entry for the bridge.
Note: Forward MAC must refer to the source MAC, and discard MAC must refer to the destination MAC.
Command Syntax
bridge <1-32> address XXXX.XXXX.XXXX (forward|discard) IFNAME
bridge <1-32> address XXXX.XXXX.XXXX (forward|discard) IFNAME vlan <2-4094>
bridge <1-32> address XXXX.XXXX.XXXX (forward|discard) IFNAME vlan <2-4094>
no bridge <1-32> address XXXX.XXXX.XXXX
no bridge <1-32> address XXXX.XXXX.XXXX vlan <2-4094>
no bridge <1-32> address XXXX.XXXX.XXXX vlan <2-4094>
Parameters
<1-32>
Bridge identifier
XXXX.XXXX.XXXX
Media Access Control (MAC) address in HHHH.HHHH.HHHH format.
forward
Forward matching frames.
discard
Discard matching frames.
IFNAME
Interface on which the frame comes out.
vlan
Identity of the VLAN in the range of <2-4094>.
Defaul
By default, bridge address is disabled
Command Mode
Configure mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#configure terminal
(config)#bridge 1 address 0000.000a.0021 forward eth0
(config)#no bridge 1 address 0000.000a.0021
(config)#bridge 1 address 0011.2222.3333 forward xe5 vlan 23
(config)#no bridge 1 address 0011.2222.3333 vlan 23
(config)#bridge 1 address 0011.2222.3333 forward xe5 vlan 11
(config)#no bridge 1 address 0011.2222.3333 vlan 11 s
(config)#bridge 1 address 0011.2222.3334 discard xe6 vlan 12
(config)#no bridge 1 address 0011.2222.3334 vlan 12
bridge ageing
Use this command to specify the aging time for a learned MAC address. A learned MAC address persists until this specified time.
Note: On XGS devices, it takes up to two ageing cycles to remove the mac entry from hardware, hence the timeout will be anywhere between mac-ageing-time to two times the mac-ageing-time. For example, if the MAC ageing time is set to 100 seconds, MAC ageing can happen anywhere between 100 to 199 seconds.
Note: The bridge aging time affects the ARP entries which are dependent upon the MAC addresses in hardware. If a MAC address ages out, it causes the corresponding ARP entry to refresh.
Use the no form of this command to set the MAC address aging time to its default (300).
Command Syntax
bridge <1-32> ageing-time (<1-240>)
bridge <1-32> ageing disable
no bridge <1-32> ageing-time
Parameters
0
Disable Ageing Time
<1-32>
Bridge group ID.
<1-240>
Aging time in minutes.
disable
Turn off MAC address aging completely.
Default
By default, the aging time is 300 seconds.
Command Mode
Configure mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#configure terminal
(config)#bridge 3 ageing-time 100
(config)#no bridge 3 ageing-time
bridge forward-time
Use this command to set the time (in seconds) after which (if this bridge is the root bridge) each port changes states to learning and forwarding. This value is used by all instances.
Use the no parameter with this command to restore the default value of 15 seconds.
Command Syntax
bridge <1-32> forward-time <4-30>
no bridge <1-32> forward-time
Parameters
<1-32>
Specify the bridge group ID.
<4-30>
Specify the forwarding time delay in seconds.
Note: Care should be exercised if the value is to be made below 7 seconds.
Default
By default, value is 15 seconds
Command Mode
Configure mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#configure terminal
(config)#bridge 3 forward-time 6
(config)#no bridge 3 forward-time
bridge hello-time
Use this command to set the hello-time, the time in seconds after which (if this bridge is the root bridge) all the bridges in a bridged LAN exchange Bridge Protocol Data Units (BPDUs). A very low value of this parameter leads to excessive traffic on the network, while a higher value delays the detection of topology change.This value is used by all instances.
Configure the bridge instance name before using this command. The allowable range of values is 1-10 seconds. However, make sure that the value of hello time is always greater than the value of hold time (2 seconds by default).
Use the no parameter to restore the default value of the hello time.
Note: A Bridge shall enforce the following relationships for Hello-time, Max-age and Forward-delay.
• 2 × (Bridge_Forward_Delay – 1.0 seconds) >= Bridge_Max_Age
• Bridge_Max_Age >= 2 × (Bridge_Hello_Time + 1.0 seconds)
Note: Hello-time is allowed only on RSTP, IEEE and Provider-RSTP types of bridges. For MSTP and Provider-MSTP hello timer is restricted.
Command Syntax
bridge <1-32> hello-time <1-10>
no bridge <1-32> hello-time
Parameters
<1-32>
Specify the bridge group ID.
<1-10>
Specify the hello BPDU interval in seconds.
Default
By default, value is 2 seconds
Command Mode
Configure mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#bridge 3 hello-time 3
(config)#no bridge 3 hello-time
bridge mac-priority-override

(config)#no bridge 1 mac-priority-override mac-address 1111.1111.1111 interface eth1 vlan 2
bridge max-age
Use this command to set the maximum age for a bridge. This value is used by all instances.
Maximum age is the maximum time in seconds for which (if a bridge is the root bridge) a message is considered valid. This prevents the frames from looping indefinitely. The value of maximum age should be greater than twice the value of hello time plus 1, but less than twice the value of forward delay minus 1. The allowable range for max-age is 6-40 seconds. Configure this value sufficiently high, so that a frame generated by root can be propagated to the leaf nodes without exceeding the maximum age.
Use the no parameter with this command to restore the default value of the maximum age.
Note: A Bridge shall enforce the following relationships for Hello-time, Max-age and Forward-delay.
• 2 × (Bridge_Forward_Delay – 1.0 seconds) >= Bridge_Max_Age
• Bridge_Max_Age >= 2 × (Bridge_Hello_Time + 1.0 seconds)
Command Syntax
bridge <1-32> max-age <6-40>
no bridge <1-32> max-age
Parameters
<1-32>
Specify the bridge group ID.
<6-40>
Specify the maximum time, in seconds, to listen for the root bridge <6-40>.
Default

Command Mode
Configure Mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#bridge 2 max-age 12
(config)#no bridge 2 max-age
bridge max-hops
Use this command to specify the maximum allowed hops for a BPDU in an MST region. This parameter is used by all the instances of the MST. Specifying the maximum hops for a BPDU prevents the messages from looping indefinitely in the network. When a bridge receives an MST BPDU that has exceeded the allowed maximum hops, it discards the BPDU.
Use the no parameter with this command to restore the default value.
Command Syntax
bridge <1-32> max-hops <1-40>
no bridge <1-32> max-hops
Parameters
<1-32>

Examples
#configure terminal
(config)#bridge 3 max-hops 25
#configure terminal
(config)#no bridge 3 max-hops
bridge priority
Use this command to set the bridge priority for the common instance. Using a lower priority indicates a greater likelihood of the bridge becoming root. The priority values can be set only in increments of 4096.

mac ageing display
Use this command to enable the display of remaining age-time value for dynamically learnt mac address.
Note: When the mac ageing display is enabled the following points are applicable .
a. The mac ageing display should be enabled in non-scaled case (i.e less than 25% of table size) .
b. High cpu usage will occurs if mac-ageing-display is enabled in scaled case.
c. When enabled ,the appropriate ageing time for each entry will only be displayed after the first iteration of the ageing thread is complete which starts after 10 seconds of the cli commit .
d. For mac entries with no active traffic, the age of the entries will be displayed based on the timestamp when the entries were first learnt. if the entries learnt time is greater than the bridge-mac-age-time (default 300secs), the age of the mac entries will be displayed as zero.
Use the no form of this command to disable the display of MAC address aging timeout. When disabled the mac-address age will be the bridge-mac-age-time default 300secs.

show bridge
Use this command to display the filtering database for the bridge. The filtering database is used by a switch to store the MAC addresses that have been learned and which ports that MAC address was learned on.
Note: The user is notified with an alert message when the MAC hardware table size is full. The notification is generated for the operator log, SNMP trap and NetConf. When the MAC table is free again due to ageing or flushing, the clear notification is generated. Table full trap is SNMP OID .1.3.6.1.4.1.36673.122.2.1.1 and table clear trap SNMP OID is .1.3.6.1.4.1.36673.122.2.1.2 .
