4.4.16.2 Statistics
The Port Channel Statistics page displays the flap count for each port channel and
their member ports. A flap occurs when a port-channel interface or port-channel
member port goes down.
To access this page, click Switching > Port Channel > Statistics .
Figure 4.238 Switching > Port Channel > Statistics
The following table describes the items in the previous figure.
Members The ports that are members of a port channel. Each port channel can
have a maximum of 8 member ports. To add ports to the port channel,
select one or more ports from the Port List field (CTRL + click to select
multiple ports). Then, use the appropriate arrow icon to move the
selected ports to the Members field.
Active Ports The ports that are actively participating members of a port channel. A
member port that is operationally or administratively disabled or does
not have a link is not an active port.
Load Balance The algorithm used to distribute traffic load among the physical ports of
the port channel while preserving the per-flow packet order. The
packet attributes the load-balancing algorithm can use to determine
the outgoing physical port include the following:

Source MAC, VLAN, Ethertype, Incoming Port

Destination MAC, VLAN, Ethertype, Incoming Port

Source/Destination MAC, VLAN, Ethertype, Incoming Port

Source IP and Source TCP/UDP Port Fields

Destination IP and Destination TCP/UDP Port Fields

Source/Destination IP and TCP/UDP Port Fields

Item Description
Item Description
Interface The port channel or member port (physical port) associated with the
rest of the data in the row.
Channel Name The port channel name associated with the port channel. For a physi-
cal port, this field identifies the name of the port channel of which the
port is a member.
Type The interface type, which is either Port Channel (logical link-aggrega-
tion group) or Member Port (physical port).
Flap Count The number of times the interface has gone down. The counter for a
member port is incremented when the physical port is either manually
shut down by the administrator or when its link state is down. When a
port channel is administratively shut down, the flap counter for the port
channel is incremented, but the flap counters for its member ports are
not affected. When all active member ports for a port channel are inac-
tive (either administratively down or link down), then the port channel
flap counter is incremented.
