NOTE: When configuring ERPM, follow these guidelines: • The Dell Networking OS supports ERPM source sessions only. Encapsulated packets terminate at the destination IP address or at the analyzer. • You can configure up to four ERPM source sessions on the switch. • You can configure any port as a source port in an ERPM session. • The maximum number of source ports that can be defined in a session is 128. • Make sure that the destination IP address is reachable via the configured IP route (static or dynamic) • The system MTU should be configured properly to accommodate the increased size of the ERPM mirrored packet. • The system encapsulates the complete ingress or egress data under GRE header, IP header and outer MAC header and sends it out at the next hop interface as pointed by the routing table. • The source IP address can be any port's ip address defined in the box but it should be unique and should not be assigned to any other system in the network. • You must specify the keyword monitor in the ACL rules used on a source interface (as shown in one of the examples following the configuration procedure). • ERPM sessions do not copy locally sourced remote-VLAN traffic from source trunk ports that carry RPM VLANs. ERPM sessions do not copy locally sourced ERPM GRE-encapsulated traffic from source ports. • A flow-based source VLAN can be monitored only for ingress traffic (not egress traffic). • You can configure the port extender as source either as a physical interface or as a VLAN, whose memebers are PEX ports or as VP lAGg. 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 Specify the source port or range of ports. Specify {rx | tx | both} the ingress (rx), egress (tx), or both ingress and egress traffic to be monitored. You can enter Port Monitoring 727

Encapsulated Remote-Port Monitoring

Encapsulated Remote Port Monitoring (ERPM) copies traffic from source ports/port-channels or source VLANs and forwards

the traffic using routable GRE-encapsulated packets to the destination IP address specified in the session.

NOTE:

When configuring ERPM, follow these guidelines:

•

The Dell Networking OS supports ERPM source sessions only. Encapsulated packets terminate at the destination IP

address or at the analyzer.

•

You can configure up to four ERPM source sessions on the switch.

•

You can configure any port as a source port in an ERPM session.

•

The maximum number of source ports that can be defined in a session is 128.

•

Make sure that the destination IP address is reachable via the configured IP route (static or dynamic)

•

The system MTU should be configured properly to accommodate the increased size of the ERPM mirrored packet.

•

The system encapsulates the complete ingress or egress data under GRE header, IP header and outer MAC header and

sends it out at the next hop interface as pointed by the routing table.

•

The source IP address can be any port's ip address defined in the box but it should be unique and should not be

assigned to any other system in the network.

•

You must specify the keyword

monitor

in the ACL rules used on a source interface (as shown in one of the examples

following the configuration procedure).

•

ERPM sessions do not copy locally sourced remote-VLAN traffic from source trunk ports that carry RPM VLANs. ERPM

sessions do not copy locally sourced ERPM GRE-encapsulated traffic from source ports.

•

A flow-based source VLAN can be monitored only for ingress traffic (not egress traffic).

•

You can configure the port extender as source either as a physical interface or as a VLAN, whose memebers are PEX

ports or as VP lAGg.

To configure an ERPM session:
