Obtaining layer 2 and 3 statistics - grstat

0	ATMP err:	can't find mobile node entry
0	ATMP err:	Invalid IP header
0	multicast	replicated, original dropped
0	multicast	TTL expired
0	multicast	packet on wrong interface
0	can't forward to/through control board

Layer 2 statistics

The grstat command reports many of the Layer 2 (data link layer) statistics currently reported by individual media card maint commands. Layer 2 statistics are reported for SP Switch Router Adapter, ATM OC-3c (ATM/Q), HSSI, Ethernet, and SONET OC-3c media cards.

List of layer 2 stats

The grstat command has options to return layer 2 data per interface or per media card.

#grstat -a l2 gt000 gt000
