Description
mtu frame size
This command configures the maximum transmission
unit frame size for all the frames transmitted and
received on all the interfaces in a switch. The
size of the MTU frame size can be increased using
this command. The value ranges between 90 and
9216.
This value defines the largest PDU that can be
passed by the interface without any need for
fragmentation. This value is shown to the higher
interface sub-layer and should not include size of
the encapsulation or header added by the
interface. This value represents the IP MTU over
the interface, if IP is operating over the
interface.
Note: Any messages larger than the MTU are divided
into smaller packets before transmission
Default: 1500
system-specific port-id <>
This command configures the system specific index
for the port. It provides a different numbering
space other than the IfIndex to identify ports.
The value ranges between 1 and 16384.
Default: 0.
