Group
Group ID
Must be a DNOS-OF L3 Unicast Group Entry.
Decrement
TTL and
do MTU
check
-
MTU check is a vendor extension. An invalid TTL (zero before or after
decrement) is always dropped and a copy sent to the CPU for forwarding
to the CONTROLLER. Similarly, a packet that exceeds the MTU is
dropped and a copy sent to the CONTROLLER. Required.
The group entry includes the decrement TTL and MTU check actions, so these need not be explicitly
specified in the action set. The Routing Flow Table counters are listed in Table 28.
Unicast Routing Flow Table expiry provisions are shown in Table 29.
