Aruba 2530 - Configuring the Switch to Filter Untagged Traffic; Displaying the Configuration; Filtering PVID Mismatch Log Messages

Configuring the switch to filter untagged traffic
Enter this command to configure the switch not to learn CDP, LLDP, or EAPOL traffic for a set of interfaces.
Syntax:
[no] ignore-untagged-mac <port-list>
Prevents MAC addresses from being learned on the specified ports when the VLAN is untagged and the
destination MAC address is one of the following:
• 01000C-CCCCCC (CDP)
• 0180c2- 00000e (LLDP)
• 0180c2-000003 (EAPOL)
Configuring the switch to ignore packet MAC address learns for an untagged VLAN
switch(config) ignore-untagged-mac 1-2
Displaying the configuration
Enter the show running-config command to display information about the configuration.
Configuration showing interfaces to ignore packet MAC address learns
switch(config) show running-config

Filtering PVID mismatch log messages
This enhancement filters out PVID mismatch log messages on a per-port basis. PVID mismatches are logged
when there is a difference in the PVID advertised by a neighboring switch and the PVID of the switch port which
receives the LLDP advertisement. Logging is an LLDP feature that allows detection of possible vlan leakage
