Concept Guide

– For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then the stack/slot/port/subport information.
– For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the stack/slot/port[/subport] information.
– For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the stack/slot/port/subport information.
– For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then the stack/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 congured, 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 congure the MAC learning limit on the interface,
enter the keywords learning-limit.
Example of the clear counters Command
When you enter this command, conrm that you want Dell EMC Networking OS to clear the interface counters for that interface.
DellEMC#clear counters te 1/1/1/1
Clear counters on TenGigabitEthernet 1/1/1/1 [confirm]

Enhanced Validation of Interface Ranges
You can avoid specifying spaces between the range of interfaces, separated by commas, that you congure by using the interface
range
command. For example, if you enter a list of interface ranges, such as interface range hu 1/1/1,fo 1/3/1, this
conguration 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-address-table static
multicast-mac-address vlan vlan-id output-range interface command.
Compressing Conguration Files
You can optimize and reduce the sizes of the conguration les.
You can compress the running conguration by grouping all the VLANs and the physical interfaces with the same property. Support to
store the operating conguration to the startup cong in the compressed mode and to perform an image downgrade without any
conguration loss are provided.
You can create groups of VLANs using the interface group command. This command will create nonexistent VLANs specied in a
range. On successful command execution, the CLI switches to the interface group context. The conguration 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 conguration in the compressed mode.
show running-config compressed and write memory compressed
The compressed conguration will group all the similar looking conguration thereby reducing the size of the conguration. For this release,
the compression will be done only for interface related conguration (VLAN & physical interfaces)
The following table describes how the standard and the compressed conguration dier:
