Command Usage
• The MAC Address Table contains the MAC addresses associated with
each interface. Note that the Type field may include the following
types:
- Learned - Dynamic address entries
- Permanent - Static entry
- Delete-on-reset - Static entry to be deleted when system is reset
• 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 8191.
