I'm hoping someone has come across this issue before and would share with me some insight.
I have a cisco infrastructure consisting of catalyst 6500 series core switches and 50 or so closet catalyst switches. In my data center, I have recently installed 3 sets of symbol wireless access switches, model 5100. I'll call these switches switch-a switch-b and switch-c.
these symbol switches have two ethernet ports, port 1 and port 2. port 1 must be in a layer2 vlan and they are, say vlan-a, vlan-b, and vlanc.
port 2 of these switches attach to a later 3 vlan. The symbo, switches map their layer 2 access ports to the layer 3 vlan according to the switch policy setup on`the symbol wireless switches.
switch-a and switch-b I have trunking enabled on the connection between these symbol switches and my cataalyst 6513. on switch-c I do not.
when I access my switch-c set, I see only the 13 access ports that reside in vlan-c, which is good. When I connecto to switches a or b, these switches report that they see access ports on all three switches, which is not good.
So, switch-a has 37 access ports in vlan-a, switch-b has 13 ports in vlan-b and switch-c has 21 access ports in vlanc, all of tese are layer 2 vlans.
I need to find out what my cisco network is propogating these l2 vlans.. switches-a and -b report 71 access ports and switch-c reports 21 access ports.
symbol stated that this is a cisco issue and that I needed to prune my vlans, or check spantree. I really don't believe the issue lies here.
I am currently sniffing vlan-b and I see only vlan-b traffic, ethertype isn't 6 but a symbol ethertype something like 8676 or something like that I don't remember.
Can anyone offer up some ideas as to why this is occuring? I'm thinking on putting a spreadsheet together showing each switches spantree priorirty as well as manually pruning my vlans I have about 31 vlans propogating thru vtp.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
