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 session only. Encapsulated packets terminate at the
destination IP address or at the analyzer.
• You can configure up to four ERPM source sessions on switch.
• Configure the system MTU to accommodate the increased size of the ERPM mirrored packet.
• The maximum number of source ports you can define in a session is 128.
• 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.
• Specify flow-based enable in case of source as VLAN or where you need monitoring on a per-
flow basis.
• Specify the monitor keyword in the access list rules for which you want to mirror.
• The maximum number of source ports that can be defined in a session is 128.
• The system allows to configure up to four ERPM sessions.
• 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.
• Source VLAN monitoring is possible only for ingress packets and is not supported for egress
direction.
• A flow-based source VLAN is monitored only for ingress traffic (not egress traffic). direction.
Changes to Default Behavior
• Rate-limiting ïs not supported for ERSPAN traffic.
• You can configure the same port as both source and destination in an ERSPAN session.
• You can configure TTL and ToS values in the IP header of ERSPAN traffic.
