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 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
Dell#show running-config interface vlan 11

The following example shows you how to configures a source as a physical interface only for ERPM.
Dell(conf)#monitor session 3 type erpm
Dell(conf-mon-sess-3)#)source vlan 100 dir rx
Dell(conf-mon-sess-3)# erpm source-ip 1.1.1.1 dest-ip 100.1.1.2
Dell(conf-mon-sess-3)# flow-based enable
Dell(conf-mon-sess-3)# no disable
The following example configures the port extender ports so that they are tagged and untagged members of VLAN 100. With
regard to the source as a VLAN, the supported direction of mirroring is rx only. You must also apply an access list to the VLAN
with the rules that match with the keyword “monitor”.
Dell(config-ext-macl)#do sh run mac

mac access-list extended test
