that are used to monitor its wireless network utilization. Trac from other clients never count against a
client's rate limits. Maximum Number of Limiters per Group: 8 inbound.
Outbound Rate: Outbound trac is sent from the network towards the client. Maximum Number of
Limiters per Group: 8 outbound.
Configure the following parameters to configure a new Bandwidth Limit:
Name
The name for the rate limit.
Average Rate (CIR)
The rate at which the network supports data transfer under normal operations. It is measured in
kilobits per second (Kbps).
The supported rate for Extreme Campus Controller is 500,000 Kbps.

VLANS
VLANs are logical subnets. Many VLANs can coexist on a single Ethernet cable (typically referred to as a
'VLAN Trunk'). The AP is a VLAN-aware bridging device. It can place trac on any VLAN to which it is
exposed. Other options are bridging locally at the controller, VxLAN, and Fabric Attach. Fabric Attach
enables the AP to connect to a Fabric Network.
It is not necessary to include a VLAN tag in a packet that is being transmitted over a VLAN. A packet
transmitted without a VLAN tag is said to be untagged. Since there is no way to identify the VLAN to
which an untagged packet belongs, there can be only one untagged VLAN on a VLAN trunk.
It is common practice to place all AP management trac on an untagged VLAN and place user trac
on tagged VLANs. Extreme Campus Controller preconfigures switches with a single untagged VLAN
that is used for managing access points and the switches themselves.
Another common option is to place all trac on a single untagged VLAN. This is a simpler option to use
when a network's applications do not benefit from VLAN deployment.
Extreme Campus Controller fully supports mixing tagged and untagged trac. An AP wired interface
can be an untagged member of one VLAN and a tagged member of several other VLANs
simultaneously.
With switches, all administrator-created VLANs in Extreme Campus Controller are classified as tagged
VLANs. When a tagged VLAN is assigned to a port, the port is configured to expect all trac received
from the VLAN or sent to the VLAN to be tagged. You can override the tagging on a per-port basis for
the ports types Host and Other.
Associate a topology to a specific device group. This enables you to define a topology that is common
to a set of devices and specify a specific attached VLAN. Topologies referenced by attached networks
or roles are automatically added to the Profile VLANS list. You can also add topologies manually to the
list. When creating a new topology, select the Profiles to associate with the new topology.
