Available Igr Bandwidth The amount of bandwidth that is currently available in the ingress
direction.
Available Egr Bandwidth The amount of bandwidth that is currently available in the egress
direction.
EXCEPT -- VALUES The Except Values display the currently available bandwidth (Avl
Bw) and currently available channels (Avl Chnl) for each class of
service: VSI-SIG, CBR, VBR-RT, VBR-nRT, UBR, ABR.
SERV-CATEG Service Category: The Class Of Service: VSI-SIG, CBR, VBR-RT,
VBR-nRT, UBR, ABR.
VAR- TYPE Variable Type: The available bandwidth (Avl Bw) or the available
channels (Avl Chnl).
VSI - SIG Virtual Switch Interface Signaling:
CBR Constant Bit Rate: Used for connections that require a high QoS and
strict cell delay variation (CDV).
VBR-RT Variable Bit Rate–Real Time: Used for connections that have burst
traffic and that require a strict cell delay variation (CDV).
VBR-nRT Variable Bit Rate–non-Real Time: Used for connections that do not
require end to end timing.
UBR Unspecified Bit Rate: Used for connections that can allow any
amount of data, up to a specified maximum, to be transmitted, but
with no guarantees in terms of cell loss rate and delay.
ABR Available Bit Rate: Used for connections that do not require timing
relationships between source and destination endpoints. ABR
provides no guarantees in terms of cell loss or delay, and provides
only a best-effort service. Cell rates are adjusted in response to the
state or condition of the network and its ability to successfully
deliver data.
