Interface Configuration (Ethernet)
Command Usage
• By default, each index number equates to a port on the switch, but can be changed to any
number not currently in use.
• If periodic sampling is already enabled on an interface, the entry must be deleted before any
changes can be made with this command.
• The information collected for each sample includes:
input octets, packets, broadcast packets, multicast packets, undersize packets, oversize
packets, fragments, jabbers, CRC alignment errors, collisions, drop events, and network
utilization.
• The switch reserves two controlEntry index entries for each port. If a default index entry is
re-assigned to another port by this command, the show running-config command will display a
message indicating that this index is not available for the port to which is normally assigned.
For example, if control entry 15 is assigned to port 5 as shown below, the show running-config
command will indicate that this entry is not available for port 8.
