Administrator Guide

• Disable a port channel.
shutdown
When you disable a port channel, all interfaces within the port channel are operationally down also.
Server Ports
By default, the MXL switch allows the server ports to come up as switch ports in no shut mode, ready to switch trac.
Default Conguration without Start-up Cong
This feature is enabled by default and can be enabled on reload by deleting the start-up cong le.
On reload, all the server ports (1-32) come up as switch ports in No Shut mode. Uplinks remain in Shut mode ensuring that there are
no network loops.
With this feature, you can install servers and test their connectivity by running applications on the servers, even before conguring
VLAN membership, STP on all interfaces or uplinks.
NOTE: This feature does not impact BMP mode. It always applies when reloading in Normal mode.
Important Points to Remember
• On a new MXL switch running the Dell Networking OS version 9.2(0.0), with no saved startup conguration, the switch comes
up with all server ports as switch ports in No Shut state. When you congure STP, the switch brings up the uplink and saves the
running conguration to the startup-cong le. All the server ports without any specic conguration have the default
conguration of Layer2 switch port and No Shut mode saved.
• On an existing MXL switch with a saved startup conguration, running an older Dell Networking OS version, an upgrade to a new
version does not change the current behavior. This is because the start-up cong le in older Dell Networking OS versions have
the default conguration of Shut mode for all the server ports without any specic conguration. To enable this feature after
upgrading a switch with a saved startup conguration, delete the start-up cong le and reboot the switch. This allows all the
server ports to come as Layer2 switch ports in No Shut state.
• In a stacked conguration of MXL switches, the behavior is similar to a standalone conguration. If a start-up cong le is
detected at bootup, the entire stack reboots using the saved conguration. If no start-up cong le is detected at restart, the
entire logical switch, including master unit, standby master, and any stack units restart with all server ports as Layer2 switch
ports in No Shut mode.
• If a new stack unit is added to an existing stack, by default, the server side interfaces always start in Shut mode. If the startup
conguration is deleted after a stack unit was added to a stack and the stack is reloaded, on reboot the entire logical switch
comes up with all server ports as Layer2 switch ports in No Shut mode.
Bulk Conguration
Bulk conguration allows you to determine if interfaces are present for physical interfaces or congured for logical interfaces.
Interface Range
An interface range is a set of interfaces to which other commands may be applied and may be created if there is at least one valid
interface within the range.
Bulk conguration excludes from conguration any non-existing interfaces from an interface range. A default VLAN may be
congured only if the interface range being congured consists of only VLAN ports.
The interface range command allows you to create an interface range allowing other commands to be applied to that range of
interfaces.
The interface range prompt oers the interface (with slot and port information) for valid interfaces. The maximum size of an
interface range prompt is 32. If the prompt size exceeds this maximum, it displays (...) at the end of the output.
NOTE: Non-existing interfaces are excluded from the interface range prompt.
