For information about S-channel and EVB, see EVB Configuration Guide.

  • Page 63: Mac-address Mac-roaming Enable

    Predefined user roles network-admin Parameters high: Assigns high MAC learning priority. low: Assigns low MAC learning priority. Usage guidelines The MAC address learning priority values can be high and low. An interface with high MAC address learning priority can learn any MAC address. An interface with low MAC address learning priority can learn only the MAC addresses that have not been learned by the high-priority interfaces.

  • Page 64: Mac-address Max-mac-count

    Usage guidelines If ports on different IRF member devices are selected ports from the same aggregation group, MAC address entries are synchronized among these IRF member devices regardless of whether MAC address synchronization is enabled for the IRF fabric. For more information about aggregation groups, see Layer 2—LAN Switching Configuration Guide.

  • Page 65: Mac-address Multiport (interface View)

    Usage guidelines This command limits the number of MAC address entries for a device. When the number of MAC address entries learned by an interface reaches the limit, the interface stops learning MAC address entries. Examples # Configure interface Ten-GigabitEthernet 1/0/1 to learn up to 600 MAC address entries. Disable the device from forwarding frames with unknown source MAC addresses after the number of learned MAC addresses reaches the upper limit.

    Usage guidelines The forward delay timer determines the time interval of state transition. To prevent temporary loops, a spanning tree port goes through the learning (intermediate) state before it transits from the discarding state to the forwarding state.
