Table 244: Port Security Statically Configured MAC Address Fields
Field
Description
Interface
Select the physical interface or the
on which to view the dynamically learned MAC
addresses.
MAC Address
This column lists the static MAC addresses, if any, configured on the selected port.
VLAN ID
Displays the VLAN ID corresponding to the statically configured MAC address.
Delete a static MAC
Address
Enter the address of the statically configured MAC address to delete. All MAC addresses
that are available to be deleted appear in the MAC Address – VLAN ID table.
VLAN ID
Enter the VLAN ID that corresponds to the statically configured MAC address to delete.
After you enter the MAC address and VLAN ID of the statically configured MAC address to delete, click
Submit
to remove the MAC address from the port and apply the new settings to the system. The screen
refreshes, and the MAC address no longer appears in the table on the page.
Port Security Dynamically Learned MAC Addresses
Use the Port Security Dynamic MAC Addresses page to view a table with the dynamically learned MAC
addresses on an interface. With dynamic locking, MAC addresses are learned on a “first arrival” basis.
You specify how many addresses can be learned on the locked port.

Managing LLDP
The IEEE 802.1AB defined standard,
LLDP (Link Layer Discovery Protocol)
, allows stations residing on an
802 LAN to advertise major capabilities and physical descriptions. This information is viewed by a
network manager to identify system topology and detect bad configurations on the LAN.
LLDP is a one-way protocol; there are no request/response sequences. Information is advertised by
stations implementing the transmit function, and is received and processed by stations implementing
the receive function. The transmit and receive functions can be enabled/disabled separately per port.
By default, both transmit and receive are disabled on all ports. The application is responsible for starting
each transmit and receive state machine appropriately, based on the configured status and operational
state of the port.
200 Series allows LLDP to have multiple LLDP neighbors per interface. The number of such neighbors is
limited by the memory constraints. A product-specific constant defines the maximum number of
