LSP accounting statistics for single-hop LSP routes
1
Brocade(config)# system-max lsp-out-acl-cam 1000
Syntax: [no] system-max lsp-out-acl-cam number
The number variable is the number of CAM entries available for LSP accounting. The default value
is 0. The valid range of this value is 0 - 16384.
NOTE
When the LSP is a trunk port, the LSP accounting feature programs multiple label ACL CAM entries,
once for each trunk port on all PPCRs.
The load-interval command can be set to a time during which the average byte and packet rates are
calculated as shown in the following.
Brocade(config-mpls)# policy
Brocade(config-mpls-policy)# load-interval 30
Syntax: [no] load-interval seconds
The seconds variable can be configured in multiples of 30 seconds within the range of 30 to 300
seconds. The default value of load-interval is 300 seconds.
SNMP agent support for ACL accounting
The SNMP agent supports the LSP tunnel byte count in MIB ifHCOutOctets, and LSP tunnel packet
count in MIB ifHCOutUcastPkts within the ifXTable.
LSP accounting statistics for single-hop LSP routes
LSP accounting statistics for single-hop LSP routes are collected on Brocade MLX Series and
Brocade NetIron XMR series devices. On an ingress LER, the number of packets and traffic bytes
forwarded through a single-hop LSP are collected. LSP accounting statistics are also collected for a
single-hop RSVP tunnel carrying multiple LDP cross connections. Data traffic and other control
protocol traffic that is forwarded by the CPU is not accounted for on single-hop LSP tunnels. LSP
accounting for a single-hop LSP is depicted in
.
NOTE
The show mpls statistics lsp command displays LSP accounting statistics for single-hop and
multi-hop LSP routes. For more information on displaying LSP accounting statistics, refer to
“Displaying LDP accounting statistics”
In the case of a LSP switchover from a multi-hop LSP to a single-hop LSP, LSP accounting statistics
are accounted for in the following scenarios.
•
In the case of an adaptive LSP, a new LSP path is being set up and traffic is re-routed onto the
new path from a multi-hop to a single-hop LSP without disabling the existing LSP path.
•
For a one-to-one Fast Reroute (FRR) failover from a multi-hop protected LSP to a single-hop
detour LSP, the LSP riding on the detour path is accounted for.
