Hi all,
About 6 months ago, we added a 5th member to our then 4-member EX4550 VC. This new switch has an 8-port 10G module installed in it:
FPC 4 REV 08 750-039070 LY0********* EX4550-32T CPU BUILTIN BUILTIN FPC CPU PIC 0 BUILTIN BUILTIN 32x 100m/1G/10G Base-T PIC 1 REV 07 711-039080 LV0********* 8x 1G/10G SFP/SFP+
The VC member ports are fed off that 10G module. The VC works and all is good on that front, but I cannot seem to query those VCPs from the plain 'show interfaces' command. Here's my 'show virtual-chassis vc-port' which does show them:
> show virtual-chassis vc-port fpc0: -------------------------------------------------------------------------- Interface Type Trunk Status Speed Neighbor or ID (mbps) ID Interface PIC / Port 0/30 Configured -1 Up 10000 2 vcp-255/0/30 0/31 Configured -1 Up 10000 1 vcp-255/0/30 fpc1: -------------------------------------------------------------------------- Interface Type Trunk Status Speed Neighbor or ID (mbps) ID Interface PIC / Port 0/30 Configured -1 Up 10000 0 vcp-255/0/31 0/31 Configured -1 Up 10000 4 vcp-255/1/0 fpc2: -------------------------------------------------------------------------- Interface Type Trunk Status Speed Neighbor or ID (mbps) ID Interface PIC / Port 0/30 Configured -1 Up 10000 0 vcp-255/0/30 0/31 Configured -1 Up 10000 3 vcp-255/0/30 fpc3: -------------------------------------------------------------------------- Interface Type Trunk Status Speed Neighbor or ID (mbps) ID Interface PIC / Port 0/30 Configured -1 Up 10000 2 vcp-255/0/31 0/31 Configured -1 Up 10000 4 vcp-255/1/1 fpc4: -------------------------------------------------------------------------- Interface Type Trunk Status Speed Neighbor or ID (mbps) ID Interface PIC / Port 1/0 Configured -1 Up 10000 1 vcp-255/0/31 1/1 Configured -1 Up 10000 3 vcp-255/0/31
And here are my 'show interfaces' commands which show me the vcp ports at 255/0/30 and 255/0/31, but nothing at 255/1/n:
> show interfaces vcp-255/0/3?
Possible completions:<interface-name> Name of physical or logical interface
vcp-255/0/30
vcp-255/0/30.32768
vcp-255/0/31
vcp-255/0/31.32768
{master:0}> show interfaces vcp-255/1/?
Possible completions:<interface-name> Name of physical or logical interface
{master:0}These two vcps also do not show up in SNMP queries of the interfaces MIB, while the others do.
The problem I am trying to solve is that we monitor the vcp-255/0/n ports within our NMS and are alerted if they go down. Since the vcp-255/1/n ports don't show up, we are forced to use the virtual chassis MIB to monitor the status of the ports, which makes things more complicated simply because of the nature of our NMS. Is there a particular reason why these ports are not available through SNMP and the CLI like the others?
