Configuring Aggregated Vlans - Dell PowerConnect B-RX Configuration Manual

This example shows a single link between the core devices. However, you can use a trunk group to
add link-level redundancy.

Configuring aggregated VLANs

A maximum of 1526 bytes are supported on ports where super-aggregated VLANs are configured.
This allows for an additional 8 bytes over the untagged port maximum to allow for support of two
VLAN tags.
To configure aggregated VLANs, configure tagged and untagged VLANs on the edge device, then
configure the aggregated and other VLANs on the core device. Perform the following tasks.
1. On each edge device, configure a separate port-based VLAN for each client connected to the
2. On each core device:

edge device. In each client VLAN:
•
Add the port connected to the client as an untagged port.
•
Add the port connected to the core device (the device that will aggregate the VLANs) as a
tagged port. This port must be tagged because all the client VLANs share the port as an
uplink to the core device.
For example, to configure device A in
following.
BigIron RX(config)# vlan 101
BigIron RX(config-vlan-101)# tagged ethernet 2/1
BigIron RX(config-vlan-101)# untagged ethernet 1/1
BigIron RX(config-vlan-101)# exit
BigIron RX(config)# vlan 102
BigIron RX(config-vlan-102)# tagged ethernet 2/1
BigIron RX(config-vlan-102)# untagged ethernet 1/2
BigIron RX(config-vlan-102)# exit
BigIron RX(config)# vlan 103
BigIron RX(config-vlan-103)# tagged ethernet 2/1
BigIron RX(config-vlan-103)# untagged ethernet 1/3
BigIron RX(config-vlan-103)# exit
BigIron RX(config)# vlan 104
BigIron RX(config-vlan-104)# tagged ethernet 2/1
BigIron RX(config-vlan-104)# untagged ethernet 1/4
BigIron RX(config-vlan-104)# exit
BigIron RX(config)# vlan 105
BigIron RX(config-vlan-105)# tagged ethernet 2/1
BigIron RX(config-vlan-105)# untagged ethernet 1/5
BigIron RX(config-vlan-105)# exit
BigIron RX(config)# write memory
Syntax: [no] vlan <vlan-id>
Syntax: [no] untagged | tagged ethernet <slot-number>/<port-number> [to
<slot-number>/<port-number> | ethernet <slot-number>/<port-number>]
The tagged command adds the port that the device uses for the uplink to the core device.
The untagged command adds the ports connected to the individual clients.
