I have two switches A and B where I would like to use RSPAN to mirror traffic to a capture server.
Switch A is a CBS350-24P-4G
Switch B is a WS-C2960X-24PD-L
Switch A is connected to Switch B via a cable from port 1 [switch A] to port 7 [switch B].
On Switch A I have set the relevant config.
interface vlan 1302
name RSPAN1
remote-span
!
interface GigabitEthernet1
switchport mode trunk
switchport trunk native vlan 1300
switchport trunk allowed vlan 1300-1302
!
monitor session 1 destination remote vlan 1302 reflector-port GigabitEthernet23 network
monitor session 1 source interface GigabitEthernet2 both
On Switch B I have the config.
vlan 1302
remote-span
!
interface GigabitEthernet1/0/7
switchport trunk allowed vlan 1300-1302
switchport trunk native vlan 1300
switchport mode trunk
power inline never
!
monitor session 1 destination interface Gi1/0/3
monitor session 1 source remote vlan 1302
However no traffic is seen on port 3 of switch B so I believe I have done something wrong. Any ideas?
On Switch A if I check the counters they are all zero. Is this expected for a reflector port?
#sh interfaces counters ge23
