state.
Information in this Display:
●
MAC Address
– source or destination address received in a frame.
●
BrPort
– the Bridge port used for forwarding traffic to the associated
MAC
address
.
●
Flags
:
◆
Static
– The entry is fixed in the software.
◆
Dynamic
– The entry was added when the address was received.
◆
LLC2
– The address is used for terminated LLC2 traffic.
All SNA frames (identified by SAP multiples of 4) will be
handled by LLC2, rather than bridged directly.
◆
Configured
– The LLC2 address has been explicitly configured for a Host
record.
◆
Native
– The addresses is accessible via a native LLC2 interface.
◆
Discovery Pending
– The MAC address was the destination address in the
received frame, and the FRX software is trying to find the correct Bridge
port for that address. (Therefore, the port will be identified as
Unk
, or
unknown, until it is discovered.)
◆
Don't Forward
– Frames to the address will not be forwarded. Addresses
with this flag are destined for the local bridge, or are reserved functional
addresses defined in the 802.1d specification and IBM Token Ring archi-
tecture.
