Differentiated Services Commands
This chapter describes the RSVP Differentiated Services (DiffServ) commands.
map-route A.B.C.D
Use this command to map a IPv4 prefix route onto a trunk. This route is to be used for packets that are mapped to a specific RSVP trunk.
Use the no parameter with this command for unmapping routes from specified trunks.

override-diffserv
Use this command to enable the Differentiated Services (Diff-Serv) override configuration.
If a Path message is received without a Diff-Serv object by a Diff-Serv enabled node, it can be interpreted either as a request for an E-LSP (EXP-Inferred-PSC LSP) or as a request for Non-Diff-Serv LSP. This command supports the override option and when configured, the LSR interprets a path message without a Diff-Serv object as a request for Non-Diff-Serv LSP.
Use the no parameter with this command disable this feature.
Command Syntax
override-diffserv
no override-diffserv
Parameters
None
Default
By default, override diffserv is disabled
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#configure terminal
(config)#router rsvp
(config-router)#override-diffserv
primary map class
Use this command to configure a primary PHB-EXP (Per-Hop Behavior-Experimental) mapping to be used by an E-LSP (EXP-Inferred-PSC LSP). This mapping is different from the node level PHB-EXP mapping.
Use the no parameter with this command to remove a PHB-EXP mapping configuration from current E-LSP PHB-EXP mapping.
Command Syntax
primary map class <0-7> exp <0-7>
no primary map class <0-7> exp <0-7>
Parameters
<0-7>
Diff-Serv class (queue) mapped to the particular PHB.
<0-7>
Exp bit which is to be mapped to this PHB.
Default
By default, primary map class is disabled
Command Mode
Trunk mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#rsvp-trunk T1
(config-trunk)#primary map class 4 exp 3

primary elsp-signaled
Use this command to configure a primary Diff-Serv (Differentiated Services) explicitly signaled E-LSP (EXP-Inferred-PSC LSP) interface.
The classes 1 to 7 are optional parameters that can be selected from node level PHB-EXP (Per-Hop Behavior) mapping as PHBs, which will then be used for an E-LSP. If you do not specify a class with this command, all classes will be selected for the E-LSP.
Use the no parameter with this command to remove the configuration.
