Description

This article explains how to check VCP port traffic utilization in a virtual chassis environment.

Symptoms

Running the show virtual-chassis or show snmp mib walk jnxUtilCounter64Value command does not display any MIB information.

Solution

The Virtual Chassis MIB has been enhanced to allow monitoring of Virtual Chassis interface statistics for EX8200 Virtual Chassis (VC).  This feature is available in Junos release 12.3.

References:

Prior to the MIB enhancement, executing the run show virtual-chassis command would not yield any output as there are no MIB's corresponding to the above "jnxUtilCounter64Value".

Example:
root@@ex4200-00# run show virtual-chassis

Preprovisioned Virtual Chassis
Virtual Chassis ID: bad4.1291.0d75
Virtual Chassis Mode: Mixed
Mstr Mixed Neighbor List
Member ID Status Serial No Model prio Role Mode ID Interface
0 (FPC 0) Prsnt XXXXXXXXXXXX ex4550-32f 129 Backup Y 1 vcp-255/1/1
                                                     1 vcp-255/1/3
1 (FPC 1) Prsnt XXXXXXXXXXXX ex4550-32f 129 Master* Y 0 vcp-255/1/1
                                                      0 vcp-255/1/3


root@@ex4200-00> show snmp mib walk jnxUtilCounter64Value

root@EX> show snmp mib walk jnxUtilCounter64Value ascii | match 4743
4743 corresponds to bps/bytes in out and CRC errors.

To gather information about the Virtual Chassis Port (VCP) interfaces and populate the Juniper MIB entries, add the script as described below.

Procedure
  1. Download the script: ex-vcp-to-mib.slax
  2. Copy the script to /var/db/scripts/op on each Routing Engine (RE)
  3. Enter Configuration mode and use the " set system scripts op file " command to set the op file to the downloaded script file (ex-vcp-to-mib.slax).
    Example:
    root@ex4200-00> start shell
    root@ex4200-00:RE:0% su
    root@ex4200-00:RE:0% pwd
    /root
    root@ex4200-00:RE:0% who
    root ttyu0 Mar 13 17:08
    root@ex4200-00:RE:0% cd /var/db/scripts/op/
    root@ex4200-00:RE:0% ls
    root@ex4200-00:RE:0% vi ex-vcp-to-mib.slax
    root@ex4200-00:RE:0% chmod 777 ex-vcp-to-mib.slax
    root@ex4200-00:RE:0% ls -al
    total 36
    drwxrws--- 2 root wheel 512 Mar 13 17:47 .
    drwxr-xr-x 6 root wheel 512 Jan 1 2010 ..
    -rwxrwxrwx 1 root wheel 12481 Mar 13 17:47 ex-vcp-to-mib.slax
    root@ex4200-00:RE:0% cli
    co{master:0}
    root@ex4200-00> configure
    Entering configuration mode

    {master:0}[edit]
    root@ex4200-00# set system scripts op file ex-vcp-to-mib.slax

    {master:0}[edit]
    root@ex4200-00# commit synchronize
    fpc0:
    configuration check succeeds
    fpc1:
    commit complete
    fpc0:
    commit complete
  4. Execute the script:  run op ex-vcp-to-mib ports all
  5. Rerun the command run show virtual-chassis vc-port ; it will now populate the values.
    Example:
    root@ex4200-00 run show virtual-chassis vc-port
    fpc4:
    --------------------------------------------------------------------------
    Interface Type Trunk Status Speed Neighbor
    or ID (mbps) ID Interface
    PIC / Port
    vcp-0 Dedicated 2 Down 32000
    vcp-1 Dedicated 1 Up 32000 5 vcp-0

    fpc5:
    --------------------------------------------------------------------------

    or ID (mbps) ID Interface
    PIC / Port
    vcp-0 Dedicated 2 Up 32000 4 vcp-1
