Administrator Guide

NOTE: If you enable more than four counter-dependent applications on a port pipe, there is an impact on line rate
performance.
The following counter-dependent applications are supported by Dell EMC Networking OS:
● Egress VLAN
● Ingress VLAN
● Next Hop 2
● Next Hop 1
● Egress ACLs
● ILM
● IP FLOW
● IP ACL
● IP FIB
● L2 ACL
● L2 FIB
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/subport 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.
○ 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.
When you enter this command, confirm that you want Dell EMC Networking OS to clear the interface counters for that
interface.

Compressing Configuration Files
You can optimize and reduce the sizes of the configuration files.
You can compress the running configuration by grouping all the VLANs and the physical interfaces with the same property.
Support to store the operating configuration to the startup config in the compressed mode and to perform an image downgrade
without any configuration loss are provided.
You can create groups of VLANs using the interface group command. This command will create nonexistent VLANs
specified in a range. On successful command execution, the CLI switches to the interface group context. The configuration
commands inside the group context will be the similar to that of the existing range command.
