Release Notes K.12.26

Enhancements

Specifying the MAC Address Format

The MAC address format command has been enhanced to allow upper-case letters to be used for the

hexadecimal numbers when indicating the MAC address in RADIUS packets for MAC-based authen-

tication.

For example, using the multi-colon-uppercase option, the MAC address would appear as follows:

AA:BB:CC:DD:EE:FF

■ Enhancement (PR_1000415155) — The ARP age timer was enhanced from the previous

limit of 240 minutes to allow for configuration of values up to 1440 minutes (24 hours) or

"infinite" (99,999,999 seconds or 32 years).

ARP Age Timer Increase

The ARP age is the amount of time the switch keeps a MAC address learned through ARP in the ARP

cache. The switch resets the timer to zero each time the ARP entry is refreshed and removes the entry

if the timer reaches the ARP age.

You can increase the ARP age timeout maximum to 24 hours or more with this command:

Syntax: aaa port-access mac-based addr-format <no-delimiter | single-dash | multi-dash | multi-colon |

no-delimiter-uppercase | single-dash-uppercase | multi-dash-uppercase |

multi-colon-uppercase>

Specifies the MAC address format to be used in the RADIUS request message.

This format must match the format used to store the MAC addresses in the

RADIUS server. (Default: no-delimiter)

no-delimiter — specifies an aabbccddeeff format.

single-dash — specifies an aabbcc-ddeeff format.

multi-dash — specifies an aa-bb-cc-dd-ee-ff format.

multi-colon — specifies an aa:bb:cc:dd:ee:ff format.

no-delimiter-uppercase — specifies an AABBCCDDEEFF format.

single-dash-uppercase — specifies an AABBCC-DDEEFF format

multi-dash-uppercase — specifies an AA-BB-CC-DD-EE-FF format

multi-colon-uppercase — specifies an AA:BB:CC:DD:EE:FF format.
