Question : no connection between cisco router and switch
|
|
i am having a problem pinging from a cisco 1751 router to a 2950 cisco switch. this is something i've done many times but nowi'm having a problem. i have a crossover cable from the router ethernet port to the switch port which i have configed as a trunk and the interface status show admin up line protocol down. then i replaced the crossover with a straight through the interface shows up up but i cant ping between the two. i have two subinterfaces configured on the router. i'll attach configs below.
router ---->

Did you actually create VLAN 10 on the switch (not just the VLAN interface)?
Peaks2950#vlan database Peaks2950(vlan)# vlan 10 VLAN 10 added: Name: VLAN0010 Peaks2950(vlan)# exit APPLY completed. Exiting....
