Reference Guide
NOTE: The MXL switch commands accept Unit ID
numbers from 0 to 5, though the MXL switch supports
stacking up to three units only with the Dell Networking
OS version 8.3.7.1.
number Enter the port number of the 40G port to be split. Enter one
of the following port numbers for the MXL switch: 48, 52, 56,
or 60.
Defaults Disabled.

History
Version 9.2(0.0) Introduced on the M I/O Aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Version 8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
Splitting a 40G port into 4x10G port is supported on standalone and stacked units.
• You cannot use split ports as stack-link to stack an MXL Switch.
• The split ports MXL switch unit cannot be a part of any stacked system.
• The unit number with the split ports must be the default (stack-unit 0).
• This set up can be verified using show system brief command. If the unit ID
is different than 0, it must be renumbered to 0 before ports are split by using
the stackunit id renumber 0 command in EXEC mode.
The quad port must be in a default configuration before it can be split into 4x10G
ports. The 40G port is lost in the config when the port is split, so be sure that the
port is also removed from other L2/L3 feature configurations.
The system must be reloaded after issuing the CLI for the change to take effect.
Port Channel Commands
A link aggregation group (LAG) is a group of links that appear to a MAC client as if they were a single link
according to IEEE 802.3ad. In the Dell Networking OS, a LAG is referred to as a Port Channel.
• For the MXL switch, the maximum port channel ID is 128 and the maximum members per port
channel is 16.
Because each port can be assigned to only one Port Channel, and each Port Channel must have at least
one port, some of those nominally available Port Channels might have no function because they could
have no members if there are not enough ports installed. In the MXL 10/40GbE Switch IO Module, those
ports could be provided by stack members.
