Nokia (formerly Alcatel-Lucent, formerly Timetra) have an extremely robust routing platform, but it has some notable differences if you’re coming from a vendor such as Cisco or Juniper (or any vendor platform in the enterprise space, really). Things like “VLANs” don’t really exist, as this is more of a metro / carrier / customer provisioning style device, so modular concepts are expected and baked into the OS at the deepest layers, unlike many of the other vendor platforms that support it but it feels like an add-in or addendum to the base routing instance. Here are a few useful commands that I threw together when I was learning SROS. As Nokia has begun rebuilding the SROS CLI to be less of a one-off, these will become less important, but until SROS is totally gone, someone will need to know them.

Show all installed line cards

show card

Contextual configuration display. From anywhere in the hierarchy, to show that sections configuration simply type


To ascertain the service ID of a given SAP (service access point)

show service sap-using

Similar to a juniper rollback compare, the SROS environment keeps candidate configurations and they can by compared, or diff’d to the running configuration. This is super useful.

admin rollback compare active-cfg to latest-rb

Also similar to juniper, it is possible to monitor the statistics of a given port in near real time

monitor port 3/2/1 interval 3 repeat 999 rate

SROS is an MPLS powerhouse, knowing how to look at the LSPs is pretty critical

show router mpls lsp terminate 
show router mpls lsp transit
show router mpls lsp
show service id <vpls-id> all
show service id <vpls-id> fdb detail

VPRN commands

show port <port> associations 
show service id <vprn-id> all
show router <vprn-id> interface
show router <vprn-id> bgp summary
show router <vprn-id> route-table
show router <vprn-id> route-table protocol bgp-vpn
show router <vprn-id> route-table <ip-address>
show router <vprn-id> bgp routes <ip-prefix>/<net-size> detail
show router <vprn-id> bgp next-hop
show router <vprn-id> bgp neighbor <ip-address> received-routes
show router <vprn-id> bgp neighbor <ip-address> advertised-routes
oam vprn-ping <vprn-id> source <ip-address> destination <ip-address>
oam vprn-trace <vprn-id> source <ip-address> destination <ip-address>

Useful BGP commands

show router bgp summary  
show router bgp neighbor <neighbor> received-routes <ipv6> 

Showing logs

show log log-id <id>
show log log-id 99
show log event-control

Showing environmentals

show chassis environment [power-supply]
show router interface [detail]
show port <port> optical

Showing and saving the configuration

admin display-config
admin save
admin save rollback
