I want to use a 2950SX (standard image IOS) as a remote distribution switch which would uplink (1000baseSX MMF) to an SX-GBIC port on a 2950G. The 2950G is connected to a 1721 router which is running several different PVC's. The different PVC's need to route to VLAN ports on the 2950SX. Can I estblish VLAN's between the Enhanced image IOS and the Standard image IOS ?
yes, this is no problem, both images support trunking (802.1q only, no ISL). So all you need to do is build trunks between the switches and the router over which to carry the VLANs...
