Correlate interface names to the right node in Network Node Group

It happens that QFabric log shows the interface name with the FPC prefix. This could be very tricky while troubleshooting. 

For instance, you can get a log line like the next one:

root@qfabric> show log messages | last 100000 | match SNMP_TRAP_LINK_DOWN
Apr 10 16:25:05 qfabric NW-NG-0 mib2d[8296]: SNMP_TRAP_LINK_DOWN: ifIndex 1091568306, ifAdminStatus up(1), ifOperStatus down(2), ifName ge-5/0/18

I think the best way to find out the FPC number of each QFX3500 node is the combination of two commands as it follows. First, log in to Network Node Group using request component login.

root@qfabric> request component login NW-NG-0

At this point, issue virtual chassis status:

qfabric-admin@NW-NG-0>

From the output abow, it shows FPC of each QFX3500 node device and the next step is to find out which serial number belongs to which node. This job can be solved showing the fabric administration inventory:

root@qfabric> show fabric administration inventory

In conclusion, for our example ge-5/0/18 matches node 9 port 18.

Checking SFP modules

Wondering how to find out remotely what SFP module is connected to any port in your QFX3500 node? then you need the following comand:

root@qfabric> show chassis hardware node-device <node_name>

Example:

Connect to QFabric's virtual IP address through SSH and from operational mode issue the command:

root@qfabric> show chassis hardware node-device nod01

Routing Engine 1          BUILTIN      BUILTIN           QFX Routing Engine

nod01            REV 04   750-999999   R9999-C           QFX3500-48S4Q

  CPU                     BUILTIN      BUILTIN           FPC CPU

  PIC 0                   BUILTIN      BUILTIN           48x 10G-SFP+

    Xcvr 0       REV 01   740-021309   APQ3DLL           SFP+-10G-LR

    Xcvr 2       REV 01   740-021309   APQ3DM4           SFP+-10G-LR

    Xcvr 6       REV 02   740-013111   D250924           SFP-T

    Xcvr 7       REV 02   740-011613   PPM20MK           SFP-SX

It only shows ports that have a transceiver (XCVR) connected in it.

If there is any port that doesn't have a SFP, it just won't show up. You can double check with:

root@qfabric# run show interfaces terse | match nod01

nod01:xe-0/0/0          up    down

nod01:xe-0/0/2          up    down

nod01:ge-0/0/6          up    up

nod01:ge-0/0/6.0        up    up   eth-switch

nod01:ge-0/0/7          up    down

nod01:ge-0/0/7.0        up    down eth-switch

Matching both commands, you can say that nod01:xe-0/0/0 has a transceiver type of SFP+-10G-LR, which is a 10 Gbit/s Ethernet over monomode fiber.
