MTU . For bridged Ethernet interfaces, the operational MTU is the lesser of the
following two values:
■
The administrative MTU of the bridged Ethernet interface
■
The administrative MTU of the underlying ATM 1483 subinterface
You can also use the bridge1483 mtu command in a profile to configure a nondefault
MTU size for a dynamic bridged Ethernet interface. For information, see “Configuring
a Dynamic Interface from a Profile” on page 563 in “Configuring Dynamic Interfaces”
on page 515.
bridge1483 mtu
■
Use to set the maximum allowable size, in bytes, of the MTU for bridged Ethernet
interfaces.
■
Specify an MTU size in the range 64–9180 bytes.
■
Example
host1(config-subif)# bridge1483 mtu 1684
■
Use the no version to restore the default MTU size for bridged Ethernet interfaces,
1518 bytes.
■
See bridge1483 mtu.
Monitoring Bridged Ethernet
You can:
■
Display information about bridged Ethernet interfaces by using the show
bridge1483 interface command.
■
Monitor MAC address validation by using the show ip mac-validate interface
command.
■
Display information about VLANs configured on bridged Ethernet interfaces by
using the
show vlan subinterface command.
Bridged Ethernet interfaces are not bound to a specific virtual router (VR).
NOTE: The E120 and E320 routers output for monitor and show commands is
identical to output from other E Series routers, except that the E120 and E320 routers
output also includes information about the adapter identifier in the interface specifier
(
slot / adapter / port ).
