Dell#
You can remove the inactive VLANs that have no member ports using the following command:
Dell#configure
Dell(conf)#no interface vlan vlan-id
vlan-id — Inactive VLAN with no member ports
You can remove the tagged VLANs using the no vlan tagged vlan-range command. You can remove the untagged
VLANs using the no vlan untagged command in the physical port/port-channel.
Port Channel Interfaces
Port channel interfaces support link aggregation, as described in IEEE Standard 802.3ad.
This section covers the following topics:
● Port Channel Definition and Standards
● Port Channel Benefits
● Port Channel Implementation
● Configuration Tasks for Port Channel Interfaces
Port Channel Definition and Standards
Link aggregation is defined by IEEE 802.3ad as a method of grouping multiple physical interfaces into a single logical interface—
a link aggregation group (LAG) or port channel.
A 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 interface.
A port channel provides redundancy by aggregating physical interfaces into one logical interface. If one physical interface goes
down in the port channel, another physical interface carries the traffic.
Port Channel Benefits
A port channel interface provides many benefits, including easy management, link redundancy, and sharing.
Port channels are transparent to network configurations and can be modified and managed as one interface. For example, you
configure one IP address for the group and that IP address is used for all routed traffic on the port channel.
With this feature, you can create larger-capacity interfaces by utilizing a group of lower-speed links. For example, you can build
a 40-Gigabit interface by aggregating four 10-Gigabit Ethernet interfaces together. If one of the five interfaces fails, traffic is
redistributed across the three remaining interfaces.
