Clearing Interface Counters

The counters in the show interfaces command are reset by the clear counters command. This
command does not clear the counters any SNMP program captures.
To clear the counters, use the following the command.
• Clear the counters used in the show interface commands for all VRRP groups, VLANs, and physical
interfaces or selected ones. Without an interface specified, the command clears all interface counters.
EXEC Privilege mode
clear counters [interface] [vrrp [vrid] | learning-limit]
(OPTIONAL) Enter the following interface keywords and slot/port or number information:
– For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port
information.
– For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
– For a Loopback interface, enter the keyword loopback then a number from 0 to 16383.
– For the Management interface on the stack-unit, enter the keyword ManagementEthernet then
the slot/port information. The slot range is from 0 to 1. The port range is 0.
– For a port channel interface, enter the keywords port-channel then a number.
– For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
– (OPTIONAL) To clear statistics for all VRRP groups configured, enter the keyword vrrp. Enter a
number from 1 to 255 as the vrid.
– (OPTIONAL) To clear unknown source address (SA) drop counters when you configure the MAC
learning limit on the interface, enter the keywords learning-limit.
Example of the clear counters Command
When you enter this command, confirm that you want Dell Networking OS to clear the interface counters
for that interface.

Enhanced Validation of Interface Ranges

This functionality is supported on the S4820T platform.
You can avoid specifying spaces between the range of interfaces, separated by commas, that you
configure by using the interface range command. For example, if you enter a list of interface ranges,
such as interface range fo 2/0-1,te 10/0,gi 3/0,fa 0/0, this configuration is considered
valid. The comma-separated list is not required to be separated by spaces in between the ranges. You
can associate multicast MAC or hardware addresses to an interface range and VLANs by using the mac-
