ISCOM2600G-HI (A) Series Configuration Guide
Bandwidth guarantee
The bandwidth guarantee function guarantees that the traffic entering the network is within
the defined range, and it discards or schedules packets. Bandwidth guarantee can meet users'
requirements on service bandwidth, and also protect network resources and carriers' benefits.
By configuring the bandwidth guarantee profile and applying it to an interface, you can mark
different flows green, yellow, and red. The ISCOM2600G-HI series switch takes different
actions over flows of different colors: forward green flows, schedule yellow flows, and
discard red flows.
Hierarchical bandwidth guarantee
Hierarchical bandwidth guarantee is more flexible. You can configure the token bucket action
or aggregation token bucket for each flow independently and then configure hierarchical
token buckets to limit the sum of multiple flows.
Color-aware and marking
If enabled with color-aware, the ISCOM2600G-HI series switch is in color-aware status, in
which it can identify whether the ingress flow is marked with color. If disabled with color-
aware, the ISCOM2600G-HI series switch is in color-blind status, in which it can neglect
whether the ingress flow is marked with color, but identify the flow color again.
The function of color marking judges the color of a flow according to Committed Information
Rate (CIR), Committed Burst Size (CBS), Excess Information Rate (EIR), and Excess Burst
Size (EBS) configured in the bandwidth guarantee profile, and modifies the flag bit to mark it
with color according to the packet format defined in IEEE 802.1ad.
