To view the congured static routes for the management port, use the show ip management-route command in EXEC
privilege mode.

VLAN Membership
A virtual LAN (VLANs) is a logical broadcast domain or logical grouping of interfaces in a LAN in which all data received is kept locally
and broadcast to all members of the group. In Layer 2 mode, VLANs move trac at wire speed and can span multiple devices. Dell
Networking OS supports up to 4093 port-based VLANs and one default VLAN, as specied in IEEE 802.1Q.
VLAN provide the following benets:
• Improved security because you can isolate groups of users into dierent VLANs.
• Ability to create one VLAN across multiple devices.
On an Aggregator in standalone mode, all ports are congured by default as members of all (4094) VLANs, including the default
VLAN. All VLANs operate in Layer 2 mode. You can recongure the VLAN membership for individual ports by using the vlan
tagged or vlan untagged commands in INTERFACE conguration mode (Conguring VLAN Membership). Physical Interfaces
and port channels can be members of VLANs.
NOTE: You can assign a static IP address to default VLAN 1 using the ip address command. To assign a dierent
VLAN ID to the default VLAN, use the default vlan-id vlan-id command.
Following table lists out the VLAN defaults in Dell Networking OS:
Feature
Default
Mode Layer 2 (no IP address is assigned)
Default VLAN ID VLAN 1
Default VLAN
When an Aggregator boots up, all interfaces are up in Layer 2 mode and placed in the default VLAN as untagged interfaces. Only
untagged interfaces can belong to the default VLAN.
By default, VLAN 1 is the default VLAN. To change the default VLAN ID, use the default vlan-id <1–4094> command in
CONFIGURATION mode. You cannot delete the default VLAN.
Port-Based VLANs
Port-based VLANs are a broadcast domain dened by dierent ports or interfaces. In Dell Networking OS, a port-based VLAN can
contain interfaces from dierent stack units within the chassis. Dell Networking OS supports 4094 port-based VLANs.
Port-based VLANs oer increased security for trac, conserve bandwidth, and allow switch segmentation. Interfaces in dierent
VLANs do not communicate with each other, adding some security to the trac on those interfaces. Dierent VLANs can
communicate between each other by means of IP routing. Because trac is only broadcast or ooded to the interfaces within a
VLAN, the VLAN conserves bandwidth. Finally, you can have multiple VLANs congured on one switch, thus segmenting the device
Interfaces within a port-based VLAN must be in Layer 2 mode and can be tagged or untagged in the VLAN ID.
