Setup
I have switch1 and 2 connected via port 1with Q trunk configured (all
vlans allowed)
Switch 1 has router R1 connected to port 20.
Switch 2 has router R2 connected to port 20.
Every thing is on VLAN 20 and both routers can ping each other.
R1 -- SW1 -- fa0/1 -- trunk -- fa0/1 -- SW2 ---R2
I am trying to config span source as port 1 on sw1, destination on sw 1
is port 48
when I configure
monitor sess 1 source int fa 0/1
monitor sess 1 dest int fa 0/48
or
monitor session 1 source interface Fa0/1
monitor session 1 destination interface Fa0/48 ingress vlan 20
I can see ping on sniffer
but when I configure
monitor sess 1 source int fa 0/1
monitor sess 1 dest int fa 0/48 encap dot1q
or
monitor sess 1 source int fa 0/1
monitor sess 1 dest int fa 0/48 encap dot1q ingress vlan 20
FAILS ...... I see nothing on sniffer.
Any one see problem with this ?
How can I see dot1q tags on the traffic? Any scenarios?
TIA
