I have 2 3120 switches..
..dhcp gave one switch an ip
address of 192.168.7.224 the other 7.234 and a default gateway of 192.168.7.1 (vlan1). The switch have 2 uplink connections to the same IDF switch each
Previous to that-all 4 switchports were set as access ports....from idf to new switch..all 4 ports were access for vlan 17
However after I changed 1 port on the new switch and one switch on the IDF swith to trunk mode.I was unable to connect from my pc..wich is on another network...i could only connect from my the IDF switch
VLAN 1 is the default vlan..
I can still connect from the switch that I have not made changes too..
here is the switch that is still working
SW1#sh cdp ne
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone
Device ID Local Intrfce Holdtme Capability Platform Port ID

3-2-4-SW1#sh int trunk
-3-2-4-SW1#
SW1#sh ip route
Default gateway is 192.168.7.1
Host Gateway Last Use Total Uses Interface
ICMP redirect cache is empty
now here is the switch that i cant connect to remotely...only from the IDF uplink it is directly connected to

Gi1/0/25 1-4094
trunk appears to be fine on the IDF switch
there is no IP address associated in the same subnet on the IDF switch as the new switches..
however im not sure this is an issue since one switch is working fine and the other is not...only after i switched just one port to trunking...
even the secondary link wouldnt provide connectivity
