Modular L3 Ethernet Switch User's Guide
♦ Description – The user-defined description of the profile.
♦ Profile Type – The type of forwarding service to be applied to packets. The possible values are:
◊
BandwidthGuarantee – Defines the bandwidth size for packets being forwarded.
Packets must meet the bandwidth requirements to be forwarded. Packets exceeding
the defined bandwidth size are dropped.
◊
minbandwidthGuarantee – Defines the minimum bandwidth size for packets being
forwarded. Packets beyond the defined bandwidth size receive a best-effort forwarding
priority.
◊
minDelay – Forwards packets with a priority of real time forwarding. Packets
exceeding the assigned amount of bandwidth are dropped.
◊
minDelayPerSession – Defines the amount of bandwidth per session for a real time
forwarding priority. Sessions exceeding the defined amount of sessions are dropped.
♦ Rate (kbps) > 440 – The rate in kilobits/seconds assigned to a profile for forwarding a packet.
The values are 0-12 Gbps depending on the output port.
♦ Max Session – Max Session is only relevant to the minDelayPerSession profile type. Indicates
the maximum number of sessions that can occur for a profile instance.
♦ New VPT – The VPT (VLAN Priority Tag). The possible values are 0-7. Zero is the default. The
higher the Vpt tag value the higher the forwarding priority.
♦ New ToS – Type of Service. Enables you to override the ToS value. The possible values are 0-3.
♦ Burst Size (bytes) – The amount of bytes that can be forwarded back-to-back faster than
normal speed. If the value is 0, the device uses a predefined value. The default size is 0. If the
burst size value is 0, the value for minDelayPerSession and minDelay is 1,536 bytes.
MinbandwidthGuarantee and BandwidthGuarantee are forwarded with a value of 3x 1,536 bytes.
To add a new profile:
1. Display the QOS Profile Table.
2. Double-click an empty row in the QOS Profile Table.
or
Click . The Insert Profile window opens. The Insert Profile window has two tabs:
♦ Main tab – Displays the main options for assigning profiles including the profiles
description, type, rate, maximum sessions, and new Vpt. The default tab is the Main tab.
♦ Advanced tab – Displays advanced options for assigning profiles including new ToS
and burst size.
