Configuring the LAN Chapter 3
Managing LAN/WAN Interfaces
 Packet filtering - the interface will receive:
– All broadcast packets
– All multicast packets
– Unicast packets which have the MAC addresses of the device
 Maximum Receive Unit (MRU) - all frames less than or equal to 1518
bytes are accepted including the 4-byte FCS.
 Oversized packets greater than 1518 bytes are not accepted.
 Runt packets of 64 bytes or less are not accepted.
 Maximum Transmission Unit (MTU) - all frames less than or equal to
1518 bytes are accepted. MTU size is set using the
ip mtu command.
 Speed is enabled using the
speed command with the following
options:
– 10 - 10 Mbps
– 100 - 100 Mbps
– 1000 - 1000 Mbps
– Auto - Auto-negotiate (default)
 Statistics - all MIB-II interface statistics are supported
 Clear commands such as
clear counters FastEthernet and
clear counters gigabitethernet
, which reset the MIB-II counters,
and
clear interface FastEthernet and clear interface
GigabitEthernet
, which reset the interface counters and facilitate
interface troubleshooting.
Configuring the LAN
Enter the following commands to configure FastEthernet interface 1 on
network 192.57.99.32:
XSR(config)#interface fastethernet 1
XSR(config-if<F1>)#ip address 192.57.99.32 255.255.255.0
XSR(config-if<F1>)#no shutdown
Enter the following commands to configure GigabitEthernet interface 2 on
network 192.168.57.12:
XSR(config)#interface gigabitethernet 2
XSR(config-if<G2>)#ip address 192.168.57.12 255.255.255.0
XSR(config-if<G2>)#no shutdown
