Establishing a Baseline for IPv6 Statistics

IPv6 statistics are stored in system counters. The only way to reset the system counters is to reboot the system. You can, however, establish a baseline for IPv6 statistics by setting a group of reference counters to zero (0).

The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.

You can use the delta keyword with IPv6 show commands to specify that baselined statistics are to be shown.

You can establish a baseline for IPv6 statistics with the following tasks:

• Setting a Baseline for IPv6 Statistics
• Setting a Baseline for IPv6 Interface Statistics
• Setting a Baseline for IPv6 Local Address Pool Statistics
• Setting a Baseline for IPv6 TCP Statistics

Setting a Baseline for IPv6 Statistics

You can set a baseline for IPv6 statistics using the baseline ipv6 command. You can use the udp keyword to set a baseline for UDP statistics.

Note: You must configure an IPv6 license using the license ipv6 command before using the IPv6 routing protocol configuration commands on the E Series router. All IPv6 routing protocol-related configurations are removed from the virtual router when you issue the no ipv6 command.

To set a baseline for IPv6 statistics:

• Issue the baseline ipv6 command in Privileged Exec mode.
  host1#baseline ipv6

Setting a Baseline for IPv6 Interface Statistics

You can set a statistical baseline for a specified IPv6 interface using the baseline ipv6 interface command.

Note: You must configure an IPv6 license using the license ipv6 command before using the IPv6 routing protocol configuration commands on the E Series router. All IPv6 routing protocol-related configurations are removed from the virtual router when you issue the no ipv6 command.

To set a statistical baseline for a specified IPv6 interface:

• Issue the baseline ipv6 interface command in Privileged Exec mode.
  host1#baseline ipv6 interface atm 2/0.100

Setting a Baseline for IPv6 Local Address Pool Statistics

To set a baseline for IPv6 local address pool statistics used in DHCP prefix delegation:

• Issue the baseline ipv6 local pool command in Privileged Exec mode.
  host1#baseline ipv6 local pool

Setting a Baseline for IPv6 TCP Statistics

You can use the baseline tcp command to set a statistics baseline for all (both IPv4 and IPv6) TCP statistics or for only IPv4 or IPv6 statistics.

Note: You must configure an IPv6 license using the license ipv6 command before using the IPv6 routing protocol configuration commands on the E Series router. All IPv6 routing protocol-related configurations are removed from the virtual router when you issue the no ipv6 command.

To set a statistics baseline for IPv6 TCP statistics:

• Issue the baseline tcp command with the ipv6 keyword in Privileged Exec mode.
  host1#baseline ipv6 tcp

To set a statistics baseline for all TCP statistics:

• Issue the baseline tcp command in Privileged Exec mode.
  host1#baseline tcp
