Bandwidth Calculation
Cisco devices running IOS or IOS-XR can calculate bandwidth. To support this functionality, all
ports and interfaces now have four new filterable attributes:
• Ingress Bandwidth (the ingress bandwidth in bps)
• Ingress Bandwidth Type (the type of calculation used to determine the ingress bandwidth)
• Egress Bandwidth (the egress bandwidth in bps), and
• Egress Bandwidth Type (the type of calculation used to determine the egress bandwidth).
Types of Bandwidth Calculation
The ways to arrive at a bandwidth number appear here in order, from highest priority to lowest
priority. If OpenManage Network Manager can calculate bandwidth in more than one way for a
particular port/interface, it uses the highest priority calculation type.
NOTE:
If a port or interface's Administrative State is not Up, its bandwidth will always be 0, regardless of the
calculation type!
CONFIGURED —This means OpenManage Network Manager has a QoS policy configured
directly against this port or interface. For example: a policer, shaper, or queuing policy. Policies
applied to
input affect the ingress bandwidth, output affect the egress bandwidth.
TRUNK AGGREGATION —This calculation means a port is in trunking mode and calculates its
bandwidth from its access ports. Essentially, if a trunk shares a VLAN with any access port,
that access port adds its bandwidth values to the trunk port's totals. This reverses ingress and
egress values. The total ingress bandwidth of the access ports becomes the egress bandwidth
of the trunk port, and the total egress bandwidth of the access ports becomes the ingress
bandwidth of the trunk port. If a port in this configuration is no longer in trunking mode, it
reverts to UNCONFIGURED.
