Hi All, we have a weird case here:
Nexus5020:
NXOS:5.1(3)N1(1a),
Eth1/1 with SFP-1000BASE-T (GLC-T)
Catalyst 2960G
int Gi0/1
both equipment connected with a crossover cable to those mentioned interfaces, after doing a shut on the nexus side (eth1/1), the catalyst stills shows the port up!!! could it be considered a normal behaivor? we would like that when shutting an interface on the nexus side the catlayst side see it down/down as happens between catalysts.
thanks a lot

I have seen some cases where the port stays up, this was due to a bad cable. If you do a 'show int E1/1 and show int gi0/1 on the switches, do both show 1gb "full"?
Could you try replacing the cable, and also I don't believe you would need a cross-over. You should be able to use a straight-thru.

You would need crossover if autoMDIX or Auto duplex/speed detection is enabled. Use Straight thru only when you hard code speed and duplex which disables autoMDIX.....

Krun - actually this is how it works
Auto-MDIX: Auto speed and auto duplex, however any cable type, crossover or straight thru can be used
Disabled Auto-MDIX: Speed and duplex can be hard coded however a crossover must be used
