We have a 6509 12.2(18)SXF5 with 720 Supervisor Engine,
and these modules:
1 5 Communication Media Module
2 8 8 port 1000mb GBIC Enhanced QoS
3 48 48 port 10/100 mb RJ45
4 48 48 port 10/100 mb RJ45
5 48 48 port 10/100 mb RJ45
6 2 Supervisor Engine 720 (Active)
7 48 48 port 10/100 mb RJ45
8 48 SFM-capable 48 port 10/100/1000mb RJ45
9 16 16 port GE RJ45
The switch is confiured as a core switch and has numerous VLANs with Layer 3 interfaces.
The switch routes across these VLANS.
When I first got here at this comapny, I noticed numerous ports in several of the blades not being used.
Today, I found out why.
When a workstation is plugged into one of these ports, the interface shows Up and I can see the input and output counters incrementing on the "sh int" for that port.
The known good workstation will not get a DHCP address or pass traffic even with a static IP config for the respective VLAN. The workstation NIC shows traffic leaving the interface, but none entering.
No logs in the switch pointing to a problem.
After verifying the physical connectivity from the four workstations I was trying to link up, I had to methodically go through the blades and find one of the unused ports that would pass traffic.
No port security issues, or configuration issues, everything is identical on the switchports, all ports have identical configuration.
Out of the four 48 port blades, two of them had sporadic ports that would not link up, all others are being used. Those two were the only ones I tried.
I had five ports on one of the blades that would not work, all others were ok, all identical config in the same VLAN and using the same workstation.
Is this a common thing with the 6509 switch or a known issue?
