Multicast: 
Displays the number of good multicast packets received or 
transmitted on the port. The error frames are not counted in. 
Unicast: 
Displays the number of good unicast packets received or 
transmitted on the port. The error frames are not counted in. 
Alignment Errors: 
Displays the number of the received packets that have a bad 
Frame Check Sequence (FCS) with a non-integral octet 
(Alignment Error). The length of the packet is between 64 bytes 
and 1518 bytes. 
UndersizePkts: 
Displays the number of the received packets (excluding error 
packets) that are less than 64 bytes long.

packets) that are 64 bytes long. 
Pkts65to127Octets: 
Displays the number of the received packets (including error 
packets) that are between 65 and 127 bytes long. 
Pkts128to255Octets:

packets) that are between 256 and 511 bytes long. 
Pkts512to1023Octets: 
Displays the number of the received packets (including error 
packets) that are between 512 and 1023 bytes long. 
PktsOver1023Octets:

packets) that are over 1023 bytes. 
Collisions: 
Displays the number of collisions experienced by a port during 
packet transmissions. 
5.4  MAC Address 
The main function of the switch is forwarding the packets to the correct ports based  on the 
destination MAC address of the packets. Address Table contains the port-based MAC address 
information, which is the base for the switch to forward packets quickly. The entries in the Address 
Table can be updated by auto-learning or configured manually. Most entries are generated and 
updated by auto-learning. In the stable networks, the static MAC address entries can enhance the 
efficiency of packets forwarding remarkably, and the address filtering feature allows the switch to 
filter the undesired packets and forbid its forwarding so as to improve the network security. 
The types and the features of the MAC Address Table are listed as the following:
