Specify the ingress (rx), egress (tx), or both
ingress and egress traffic to be monitored.
You can enter mulitple source statements
in an ERPM monitoring session.
5
erpm source-ip-address dest-ip-
address
Specify the source IP address and the
destination IP address to which
encapsulated mirrored traffic is sent.
6
flow-based enable
Specify ERPM to be performed on a flow-
by-flow basis or if you configure a VLAN
source interface. Enter no flow-based
disable to disable flow-based ERPM.
7
no disable
Enter the no disable command to
activate the ERPM session.
The following example shows a sample ERPM configuration.
Dell(conf)#monitor session 0 type erpm
Dell(conf-mon-sess-0)#source tengigabitethernet 0/9 direction rx
Dell(conf-mon-sess-0)#source port-channel 1 direction tx
Dell(conf-mon-sess-0)#erpm source-ip 1.1.1.1 dest-ip 7.1.1.2
Dell(conf-mon-sess-0)#no disable
Dell(conf)#monitor session 1 type erpm
Dell(conf-mon-sess-1)#source vlan 11 direction rx
Dell(conf-mon-sess-1)#erpm source-ip 5.1.1.1 dest-ip 3.1.1.2
Dell(conf-mon-sess-1)#flow-based enable
Dell(conf-mon-sess-1)#no disable
Dell# show monitor session

The next example shows the configuration of an ERPM session in which VLAN 11 is monitored as the source
interface and a MAC ACL filters the monitored ingress traffic.
