mikej412 Member Posts: 10,086 ■■■■■■■■■■The 2950 only supports dot1q
The 2900 probably defaults to ISL -- depending on the version of 2900, you might support dot1q encapsulation already, or be able to upgrade to a switch IOS that does.
You are using a cross-over cable, right?:mike: Cisco Certifications -- Collect the Entire Set! -
Aquabat [banned] Inactive Imported Users Posts: 299yea it's an o-xver, i figuered it might be encap.
as i recall there is no encap command on 2950 since it's only dot1q. i'll tryt to encap on the 2900. This makes me feel so stupid, lo
THanks for the help chiefi herd u leik mudkips lol -

Aquabat [banned] Inactive Imported Users Posts: 299yes that too.
i run a no shut on my int vlan 2 but it still says administravily shut. even though i no shut it.
any ideas?i herd u leik mudkips lol -
networker050184 Mod Posts: 11,962 ModTry to shut int vlan 1 first then no shut int vlan 2.An expert is a man who has made all the mistakes which can be made.

Aquabat [banned] Inactive Imported Users Posts: 299i will once i get home. Do you know if the 2900 defaults to IEEE?
i tihnk my ios is buggin on it also. cause i get the
encap - incomplete command
encapsulation - never heard of this command
output, i hate that. ya know how to tab complete it and it doesn't work. but it still says incomplete command. so annoyingi herd u leik mudkips lol -
networker050184 Mod Posts: 11,962 ModIf the switch only supports one type of encapsulation the command is not available.An expert is a man who has made all the mistakes which can be made.

interface fast 0/12
"switchport mode trunk
switchport trunk encapsulating ("dot1q or isl")
make bot the interface force to full duplex , 100 mb
Before unshutting vlan 2 make the trunk between both the switch up and create the VLAN2 in vlan database .
config t
vlan database
vlan 2
Do sh vlan and check if you are able to see vlan 2 created in the output and then unshut the VLAN svi
Int vlan 2
no shut
try this out -
mwgood Member Posts: 293Keep in mind that a layer-2 only switch only supports a single management vlan interface. Typically, this is going to be vlan 1 unless modified.
Just as a suggestion - you may want to move your switch IPs over to vlan 1 on both sides.
The 3550 & above would work quite differently.
