System FDB

The FDB system allows the user to view the fdb or forwarding database. This involves the Layer 2 (Ethernet MAC) and Layer 3 (IP) learned information.

System Forwarding Data Base (FDB)

• Command Path – show>tolt>system>
• Action – show
• Module – tolt
• Container – system
• Types – 
  • Phys address – Displays IP Address for this sub-string. Field length is limited to xx characters. Example:172.25.123.45
    Note: There can be up to 4 IP address bindings per MAC address and is displayed a1s 4 entries. The IP address may be blank if no binding is learned by the system.
    • string
  • VLAN ID –.Represents the VLAN identifier. Values range from 2 through 4094, with 10 VLANs reserved for internal use.
    • string
  • AID – Displays the access identifier (AID) of the port. Example: Net 3..
  • Age – Displays the age of the MAC address.
    • string
  • Address – Displays the  MAC address of the device associated with the port.
    • true | false
  • MAC – Displays whether there is a Sticky MAC associated with the MAC Address (true/false). 
    Note: If there is a Sticky MAC, it dynamically associates the mac-address to the respective port.
    • string
  • Time – Indicates the amount of time that DHCP snooping is allowed when DAI is used.
    • string

System fdb l2 Show Example

The fdb l2 command gives all the learned MAC entries in the system.

• Command Path – show>tolt>system>
• Action – show
• Module – tolt
• Container – system
• Types – Example Parameters
  • fdb l2

1. From the MDS1-ESUA# command line, input show tolt system fdb l2, and press Enter. 
2. Outputs similar to the following are displayed:

MDS1-ESUA# show tolt system fdb l2 <enter>
                   VLAN
PHYS ADDRESS       ID    AID   AGE

System fdb l3 Show Example

The fdb L3 command gives all the learned IP addresses that were learned during DHCP snooping.  DHCP snooping is only performed if DAI is enabled.
