Default switchport setting for 3500xl series

[OldSkoolSkater]

Hello All

What is the default switchport mode setting for the 3500xl series?
Is it access, trunk, or auto?

Our 2950's default to auto, and any changes are reflected in the show running-config of the switch.
When I make changes on the 3500's though and do a show run, there are no entries on the port listings to indicate what the switchport mode is set to!!

Help!

If the port is set to default it won't show anything. wich means that a port is default:

access, auto speed and auto duplex

you can check the speed and duplex by doing a show int FastEthernet 0/x (where x is the port number)

show run:

interface FastEthernet0/1
duplex full
speed 100
switchport mode trunk

corresponding show int faste 0/1part of it)

Encapsulation ARPA, loopback not set
Keepalive not set
Full-duplex, 100Mb/s, 100BaseTX/FX

Steve,

I beleive the 3500xl have their ports at switchport mode access as default. If you enter this for an inteface it will not show up in the configuration for that interface. Therefore if there is no switchport mode entry assume access for a 3500xl.

I think the same is the case for the 2950 excempt assume auto !?! Confusing - we found our 2950 switches suddenly started trunking with configs similiar to 3500xl's !

cheers,
Andy

Cheers for that.
As you rightly say, the 2950's default to auto - this much I know.
Thanks for clearing up the 3500XL query!

The Cisco 3500XL and 2900XL series of switches do not support auto-negotiation of Trunking, they must be forced to be either Access Ports of Trunk ports with the command:

switchport mode access/trunk

By default all the ports on the 2900XL and 3500XL are Access Ports. The newer 2950 & 3550 switch are by default in Auto state for trunking (much better product).
