Command Usage
◆ The MAC Address Table contains the MAC addresses associated with each
interface. Note that the Type field may include the following types:
■
Learn - Dynamic address entries
■
Config - Static entry
■
Security - Port Security
◆ The mask should be hexadecimal numbers (representing an equivalent bit
mask) in the form xx-xx-xx-xx-xx-xx that is applied to the specified MAC
address. Enter hexadecimal numbers, where an equivalent binary bit “0” means
to match a bit and “1” means to ignore a bit. For example, a mask of 00-00-00-
00-00-00 means an exact match, and a mask of FF-FF-FF-FF-FF-FF means “any.”
◆ The maximum number of address entries is 8K.
◆ The “Life Time” column can display the possible text strings:
■
Permanent — A persistent entry that remains in the database even after
the switch is rebooted.
■
Delete on Reset — The entry remains in the database until the switch is
rebooted (e.g. the CPU management MAC).
