www.dell.com | support.dell.com Parameters backup interface gigabit tengigabit fortygigabit slot/port Use this option to configure a redundant Layer 2 link without using Spanning Tree. This keyword configures a backup port so that if the primary port fails the backup port changes to the up state. If the primary later comes up, it becomes the backup. Enter this keyword if the backup port is a 1G port. Enter this keyword if the backup port is a 10G port. Enter this keyword if the backup port is a 40G port. Specify the stack-unit and port number of the backup port. Defaults Disabled (The interface is in Layer 3 mode.) Command Modes INTERFACE Command History Version 9.0.2.0 Version 8.3.11.1 Version 8.3.7.0 Introduced on the S6000. Introduced on Z9000 Introduced on the S4810. Usage Information If an IP address or VRRP group is assigned to the interface, you cannot use the switchport command for that interface. To use the switchport command on an interface, only the no ip address and no shutdown statements must be listed in the show config for that command. When you enable the switchport command, the interface is automatically added to the Default VLAN. To use the switchport backup interface command on a port, first execute the switchport command on the port. For details, see the section Configuring Redundant Links in the Layer 2 chapter of the FTOS Configuration Guide.

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 FTOS, a LAG is referred to as a Port Channel. Table 20-10. Port Channel Limits Platform Maximum Port Channel IDs Maximum Members per Port Channel S-Series 128 8 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 S-Series, those ports could be provided by stack members. The commands in this section are specific to Port Channel interfaces: • channel-member • group 458 | Interfaces
