Troubleshooting in BShell ( the Hardware debug level)
Display linkagg information:
BCM.0> d chg trunk_group
TRUNK_GROUP.ipipe0[3]: <TG_SIZE=1,RTAG=6,EVEN_PARITY=1,BASE_PTR=5>
TRUNK_GROUP.ipipe0[66]: <RTAG=6,>
TRUNK_GROUP.ipipe0[67]: <RTAG=6,EVEN_PARITY=1,BASE_PTR=4>
TRUNK_GROUP.ipipe0[100]: <RTAG=6,EVEN_PARITY=1,BASE_PTR=1>
TRUNK_GROUP.ipipe0[101]: <RTAG=6,EVEN_PARITY=1,BASE_PTR=2>
Verifyng LACP BPDU drop on hardware level :
The following command can be used to check status before or after an issue occurs and for monitoring purposes to
see is there any packets drop at the hardware level, and what type of packets are dropped.
Dump counters for the port used in the linkagg (in this case it's 1/1/29 corresponding to port ge28) 3 times in 30
second interval:
BCM.0> show c ge28
RUC.ge28 : 2,119 +2,119
RDBGC0.ge28 : 119,073 +119,073 1/s
RDBGC1.ge28 : 2,237 +2,237 2/s
RDBGC3.ge28 : 24 +24
ING_NIV_RX_FR.ge28 : 5,901 +5,901 2/s

R127.ge28 : 5,597 +5,597 1/s
R255.ge28 : 111,039 +111,039 2/s
...
Dump RDBGC0 counter 3 times in 30 second interval:
BCM.0> g RDBGC0.ge28
RDBGC0.ge28[1][0x38002b1e]=0x1d3cf: <EVEN_PARITY=0,COUNT=0x1d3cf>
Dump DROP_PKT_CNT_ING counter 3 times in 30 second interval:
BCM.0> g drop_pkt_cnt_ing.ge28
DROP_PKT_CNT_ING.ge28[3][0x8001001d]=0: <COUNT=0>
