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.
Note: Do not configure the local address as a map route, as explicit validation is not done. The wrong configuration may impact traffic.

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 class-to-exp-bit
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 class-to-exp-bit CLASS <0-7>
no primary class-to-exp-bit CLASS <0-7>
Parameters
CLASS
Specify the DiffServ Class Name (for example, be, ef etc.) used for selecting incoming IP packets to be mapped to a specified RSVP trunk.
<0-7>

primary elsp-signaled
