Did you enable portfast on the access ports? A switch interface is in one of two modes: access or trunk. Since you're not connecting to another switch, it's advisaable to use portfast. You can even enable portfast on an interface that connects to a router if you're not using the router/switch link in a ROAST or OAR configuration (router on a stick / one-armed router). Since the PC MAC addr shows up in the switch table but you're not able to ping the PC, it's likely that the PC doesn't have an IP addr (assuming you're using a DHCP srvr, are you?). Portfast activates the interface quickly so the exchange of messages can occur within the time slice allowed by the DHCP srvr. -- TT Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=42787&t=42783 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
