Conguring RSPAN Source Sessions to Avoid BPD Issues
When ever you congure an RPM source session, you must ensure the following to avoid BPDU issues:
1 Enable control plane egress acl using the following command:
mac control-plane egress-acl
2 Create an extended MAC access list and add a deny rule of (0x0180c2xxxxxx) packets using the following commands:
mac access-list extended mac2
seq 5 deny any 01:80:c2:00:00:00 00:00:00:ff:ff:ff count
3 Apply ACL on that RPM VLAN. In this example RPM vlan is 10.
DellEMC#show running-config interface vlan 10
!
interface Vlan 10
no ip address
mode remote-port-mirroring
tagged Port-channel 2
mac access-group mac2 out
no shutdown
4 Create Source RPM session as follows (port-channel 1 and port-channel 2 are LACP).
DellEMC(conf)#monitor session 1 type rpm
DellEMC(conf-mon-sess-1)#source port-channel 1 destination remote-vlan 10 dir rx
DellEMC(conf-mon-sess-1)#no disable
5 Show the output for the LACP.
DellEMC#show interfaces port-channel brief
Codes: L - LACP Port-channel
O - OpenFlow Controller Port-channel
