Configuring VLANs on the Switch
Summit 200 Series Switch Installation and User Guide 103
Renaming a VLAN
To rename an existing VLAN, use the following command:
config vlan name
The following rules apply to renaming VLANs:
• Once you change the name of the default VLAN, it cannot be changed back to default.
• You cannot create a new VLAN named default.
• You cannot change the VLAN name MacVlanDiscover. Although the switch accepts a name change,
once it is rebooted, the original name is recreated.
Configuring VLANs on the Switch
This section describes the commands associated with setting up VLANs on the switch. Configuring a
VLAN involves the following steps:
1 Create and name the VLAN.
2 Assign an IP address and mask (if applicable) to the VLAN, if needed.
NOTE
Each IP address and mask assigned to a VLAN must represent a unique IP subnet. You cannot
configure the same IP subnet on different VLANs.
3 Assign a VLANid, if any ports in this VLAN will use a tag.
4 Assign one or more ports to the VLAN.
As you add each port to the VLAN, decide if the port will use an 802.1Q tag.
VLAN Configuration Commands
Table 30 describes the commands used to configure a VLAN.
Table 30: VLAN Configuration Commands
Command Description
config vlan add port {tagged
| untagged} {nobroadcast} Adds one or more ports to a VLAN. You can
specify tagged port(s), untagged port(s).
Specify
nobroadcast to prevent the switch
from forwarding broadcast, multicast, and
unknown unicast traffic. By default, ports are
untagged.
config vlan delete port
{tagged | untagged} {nobroadcast} Deletes one or more ports from a VLAN.
config vlan ipaddress /
} Assigns an IP address and an optional mask to
the VLAN.
config vlan tag Assigns a numerical VLANid. The valid range
is from 2 to 4094 (1 is used by the default
VLAN).
