Deployment Guide

4.4.2.1 Naming Convention

Table 46 details the DNOS-OF L2 Interface group entry identifier subfields that encode combinations of egress

port and VLAN ID.

4.4.2.2 Action Buckets

The single action bucket specifies the output port, and whether or not the packet is egressed tagged.

Although the pop action is a NOP if the packet has no VLAN tag, packets should always have a VLAN tag

when the actions in the output group table are applied.

Note: If the packet came in untagged and a port VLAN was assigned, a VLAN tag was pushed as a VLAN Flow

Table action.

Clearly DNOS-OF L2 Interface group entries must be defined before being used. DNOS-OF maintains

reference counts for used entries, and an entry cannot be deleted if it is referenced by a flow entry or another

group.

4.4.2.3 Counters

DNOS-OF L2 Interface group entry counters are as shown in Table 48.
