Configuring the Forwarding Database
4.2.9.3 Feature Interactions for Interface Learn Limit and TPID
The SET INTERFACE TPID and SET INTERFACE LEARNLIMIT commands affect this feature.
The SBx3112 supports a maximum 16K MAC address table size. On a per-port basis, if LEARNLIMIT=OFF
•
then the port can learn up to the system maximum. If LEARNLIMIT=1..64, then the port can fully support
that limit. This applies both XE4 and GE24 interfaces.
Unlike legacy iMAP, there is a limited number of TPIDs for a given card -- that can be applied to all card
•
ports. For the XE4, the limit is 2 different TPIDs. For GE24 cards, the limit is 8 different TPIDs.
4.2.9.4 Configuration Procedure - Dynamically Clearing the FDB
The following procedure demonstrates the behavior of the FDB when MAC addresses are configured to be
dynamically cleared -- using the SET SWITCH MACREMOVALMODE command.
TABLE 4-1
Step Command
