Troubleshooting in bShell
Verify a VLAN's Spanning Tree Group (STG):
BCM.0> dump chg vlan 2
VLAN.ipipe0[2]:
<VLAN_PROFILE_PTR=1,VALID=1,STG=5,PORT_BITMAP_W1=0xc00000,PORT_BITMAP_W0=0x5f,PORT_BITMAP=0x00c00
0000000005f,ING_PORT_BITMAP_W1=0xc00000,ING_PORT_BITMAP_W0=0x5f,ING_PORT_BITMAP=0x00c000000000005
f,EVEN_PARITY_1=1,EVEN_PARITY_0=1,ENABLE_IGMP_MLD_SNOOPING=1,>
BCM.0>
Convert the port bitmat to readable format:
BCM.0> pbmp 0x5f
0x000000000000000000000000000000000000000000000000000000000000005f ==>

Verify the STG state in hardware to check if the port is mapped and configured correctly:
BCM.0> stg stp 5
STG 5:
Block: ge1-ge28,xe
Forward: ge0,hg
