To configure an ERPM session:
Step Command Description
1
configure terminal
Enter global configuration mode.
2
monitor session id type erpm
Specify a session ID and ERPM as the type of
monitoring session, and enter Monitoring-Session
configuration mode. The session number needs to
be unique and not already defined.
3
source {interface | range }
direction {rx | tx | both}
Specify the source port or range of ports. 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
SessID Source Destination Dir Mode Source IP Dest IP
------ ------ ----------- --- ---- --------- --------
0 Te 0/9 remote-ip rx Port 1.1.1.1 7.1.1.2
0 Po 1 remote-ip tx Port 1.1.1.1 7.1.1.2
1 Vl 11 remote-ip rx Flow 5.1.1.1 3.1.1.2
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.
Dell(conf)#mac access-list standard flow
Dell(config-std-macl)#seq 5 permit 00:00:0a:00:00:0b count monitor
