Reference Guide

– (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.
Dell#clear counters gi 0/0
Clear counters on GigabitEthernet 0/0 [confirm]

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-
address-table static multicast-mac-address vlan vlan-id output-range interface
command.
Compressing Configuration Files
The functionality to optimize and reduce the sizes of the configuration files is supported on the S4820T
platform.
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
non-existant 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:
int vlan 2 int vlan 3 int vlan 4 int vlan 5 int vlan 100 int vlan 1000
