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
◆ 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 16K.
