Displaying the Bridging Database

Use the Bridging Database windows to display information about MAC addresses in the bridging (or filtering) database.   You can display information about permanent, registered, reserved, static, dynamic, and VSD addresses, including:

  • Whether rate limiting is enabled for an address

  • Whether the address is a multicast address

  • The address entry type (dynamic, reserved, registered, and so on)

  • The last port on which the address was seen (dynamic, unicast static, and unicast permanent addresses only)

  • The port on which the address was learned (dynamic, unicast static, and unicast permanent addresses only)

  • The ports on which the address is allowed (permanent and static addresses only)

  • The VSD to which an address belongs

Field Descriptions

MAC Address MAC addresses in the bridging database.
VSD VSD to which this address belongs.
Type Permanent, registered, reserved, or static addresses in a range.
MC Multicast address.  The value for this field is yes if this address is a multicast address.  If the address is a unicast address, the value is no.
Rate Limit State of rate limiting.  For multicast addresses, rate limiting can be enabled or disabled.  Rate limiting is not applicable (N/A) for unicast addresses.  Rate limiting sets the maximum number of packets per second the line card is to forward for a particular MAC address, or that are of a particular protocol type. The default is 400 frames per second.
Last Seen Port Last port on which the address was seen (dynamic, unicast static, and unicast permanent addresses only).
Learned Port Port on which the address was learned (dynamic, unicast static, and unicast permanent addresses only).
Allowed Ports Ports on which the address is allowed (permanent and static addresses only).
