Platforms

7210 SAS-K 2F6C4Tand 7210 SAS-K 3SFP+ 8C

Description

This command displays extended statistics per DHCPv4 subnet in local DHCPv4 server.

The following statistics are included in the output:

the number of stable leases in the subnet
the number of provisioned address in the subnet
the number of used address in the subnet
the number of free address in the subnet
the percentage of used address
the percentage of free address

For each statistic (except for provisioned addresses), there is current value and peak value, peak value is the highest value since subnet creation or last reset via the clear router rt-id dhcp local-dhcp-server svr-name subnet-ext-stats command.

When parameter pool is used, the statistics of each subnet in the pool will be displayed.

Parameters

ip-address[/mask]: Specifies the subnet.

pool-name: Specifies the name of local DHCPv4 server pool.

Output

The following output is an example of subnet extended statistics information, and Table: Output fields: subnet extended statistics describes the output fields.

ipv4-prefix-length —		0 to 32
ipv6-prefix-length —		0 to 128 (7210 SAS-D, 7210 SAS-K 2F1C2T, 7210 SAS-K 3SFP+ 8C) 0 to 64 (7210 SAS-Dxp)

preference

Displays only static routes with the specified route preference.

Values: 0 to 65535

ip-address

Displays only static routes with the specified next hop IP address.

Values

ipv6-address —	x:x:x:x:x:x:x:x (eight 16-bit pieces)
	x:x:x:x:x:x:d.d.d.d
	x - 0 to FFFF (hexadecimal)
	d - 0 to 255 (decimal)

tag

Displays the tag used to add a 32-bit integer tag to the static route. The tag is used in route policies to control distribution of the route into other protocols.
