21.4. bShell Troubleshooting
Every SAP configured is considered as one virtual port. When a SAP is enabled, internally we will bring up
the virtual port and configure the hardware with CML flags to 8 to do hardware learning for this virtual port.
For example:
BCM.0> d chg source_vp
SOURCE_VP.ipipe0[2]:
<VFI=1,TPID_ENABLE=1,SD_TAG_MODE=1,EXP_PVLAN_VID=1,EVEN_PARITY=1,ENTRY_TYPE=1,DVP=1,DISABLE_VLAN_
CHECKS=1,DEFAULT_VLAN_TAG=1,DEFAULT_VID=1,CML_FLAGS_NEW=8,CML_FLAGS_MOVE=8,>\
When a SAP is disabled, the virtual port still exists in hardware as well as in software. But in software we
configure that virtual port down and configure hardware to set CML flag as 1 which is to drop the packet
received in this virtual port.
For example:
BCM.0> d chg source_vp
SOURCE_VP.ipipe0[1]:
<VFI=1,TPID_ENABLE=1,SD_TAG_MODE=1,EXP_PVLAN_VID=1,EVEN_PARITY=1,ENTRY_TYPE=1,DVP=1,DISABLE_VLAN_
CHECKS=1,DEFAULT_VLAN_TAG=1,DEFAULT_VID=1,CML_FLAGS_NEW=1,CML_FLAGS_MOVE=1,>
