Hi everyone,
I’m attempting to do a remote network discovery on a group of devices I’ve never seen before. When I ssh into the management IP of one of them, I see this:
RP/0/RP0/CPU0:SWITCH1#show ver Cisco IOS XR Software, Version 6.6.12 Copyright (c) 2013-2019 by Cisco Systems, Inc. Build Information: Built By : gopalk2 Built On : Fri May 24 03:37:46 PDT 2019 Built Host : iox-lnx-035 Workspace : /auto/srcarchive17/prod/6.6.12/iosxrwbd/ws Version : 6.6.12 Location : /opt/cisco/XR/packages/ Accton_as5916_54xks () processor System uptime is 9 weeks 3 days 19 hours 2 minutes RP/0/RP0/CPU0:SWITCH1# |
I’m told by a former colleague that this device functions as a L2 switch, which I guess is useful information. But how to see what the device is connected to? CDP is disabled by company requirement.
One thing I’d like to do is look at the CAM table of this device. I can track devices by MAC address in our device database, so seeing the CAM table would be a viable tool. After a lot of Google searches, I came across this post with this command:
show l2vpn forwarding bridge-domain mac-address location 0/x/CPU0 |
But I couldn’t figure out how to get that to work:
RP/0/RP0/CPU0:SWITCH1# RP/0/RP0/CPU0:SWITCH1#show l2vpn forwarding bridge-domain mac-address location ? 0/0/CPU0 Fully qualified location specification 0/RP0/CPU0 Fully qualified location specification WORD Fully qualified location specification RP/0/RP0/CPU0:SWITCH1#show l2vpn forwarding bridge-domain mac-address location 0/0/CPU0 RP/0/RP0/CPU0:SWITCH1#show l2vpn forwarding bridge-domain mac-address location 0/RP0/CPU0 RP/0/RP0/CPU0:SWITCH1#show l2vpn forwarding bridge-domain mac-address location RP/0/RP0/CPU0 show l2vpn forwarding bridge-domain mac-address location RP/0/RP0/CPU0 ^ % Invalid input detected at '^' marker. RP/0/RP0/CPU0:SWITCH1# |
Sooooo… what the heck? Am I applying the wrong command? And if I am using the right command, what is a location? Where can I read up on this? Thank you.
