Gigabit ethernet ports on 6500 switches and half duplex

[toellis]

Is it possible to set the gigabit ethernet ports on Cisco 6500 to half duplex? And even if it is, is this going to cause problems? Its just that I've read on the TAC that these ports only support full duplex.

Nope it is not possible, the easiest way to tell is if you do a sh port cap x/x - naturally applies to CatOS.

Eg:

sh port cap 4/1

Model WS-X6408-GBIC

Port 4/1

Type 1000BaseSX

Speed 1000

Duplex full

Trunk encap type 802.1Q,ISL

Trunk mode on,off,desirable,auto,nonegotiate

Channel yes

Broadcast suppression percentage(0-100)

Flow control receive-(off,on,desired),send-(off,on,desired)

Security yes

Dot1x yes

Membership static,dynamic

Fast start yes

QOS scheduling rx-(1q4t),tx-(2q2t)

CoS rewrite yes

ToS rewrite DSCP

UDLD yes

Inline power no
