HP Comware 5 Debug Manual Vol 1

Field
Description
TB Filter: COS has been set
This event is printed if the Ethernet frame filter function
is configured on the incoming/outgoing interface for
transparent bridge forwarding and the packet carries
a VLAN tag.
TB Filter: Packet has no VLAN tag, ignore COS
This event is printed if the Ethernet frame filter function
is configured on the incoming/outgoing interface for
transparent bridge forwarding and the packet carries
no VLAN tag.
It is no need to select MAC again
This event is printed when an Ethernet interface joins a
bridge set after the BVI of the bridge set borrows a
MAC address and the Ethernet interface that owns the
MAC address leaves the bridge set.

# Enable debugging for transparent bridging events on Router B. Output similar to the following example
is generated when you ping Router C from Router A under the following conditions:
•
Transparent bridging is enabled on Router B.
•
Ethernet 1/2 and Ethernet 1/3 on Router B are assigned to the same bridge set.
•
An ARP entry already exists.

// BRIDGE received a ping packet on Ethernet 1/1. BRIDGE passed the packet to the transparent
bridging module for further processing because both of the following conditions exist:
•
The incoming interface is already in the native bridge set.
•
The packet is a unicast packet and its destination MAC address is not the MAC address of the
incoming interface.
