Configuring the C-VLAN Ethertype (CLI)
The system C-VLAN Ethertype is set by the system as 0x8100.
To display the system C-VLAN ethertype, enter the following command in root view:
root> ethernet generalcfg ethertype show cvlan
Configuring the MRU (CLI)
To define the global size (in bytes) of the Maximum Receive Unit (MRU), enter the following command in root
view:
root> ethernet generalcfg mru set size <size>
To display the system MRU, enter the following command in root view:
root> ethernet generalcfg mru show

Parameter
Input Type
Permitted Values
Description
size
Number
64 to 9612
Defines the global size (in bytes) of the
Maximum Receive Unit (MRU). Frames
that are larger than the global MRU will be
discarded.
Example
For example, the following command sets the system MRU to 9612:
root> ethernet generalcfg mru set size 9612

P-20's switching fabric distinguishes between physical interfaces and logical interfaces. Physical and logical
interfaces serve different purposes in the switching fabric. In some cases, a physical interface corresponds to a
logical interface on a one-to-one basis. For some features, such as LAG, a group of physical interfaces can be joined
into a single logical interface.
The basic interface characteristics, such as media type, port speed, duplex, and auto-negotiation, are configured
on the physical interface level. Ethernet services, QoS, and OAM characteristics are configured on the logical
interface level.
