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. - 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 EMC Networking OS to clear the interface counters for that interface.

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. Two existing exec mode CLIs are enhanced to display and store the running configuration in the compressed mode. show running-config compressed and write memory compressed The compressed configuration will group all the similar looking configuration thereby reducing the size of the configuration. For this release, the compression will be done only for interface related configuration (VLAN & physical interfaces) The following table describes how the standard and the compressed configuration differ: 434 Interfaces
