# Setting Statistics Baselines for Ethernet Interfaces

You can use the baseline interface commands to establish a baseline for Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet statistics on a line module or an SRP module. The router stores statistics in counters that reset only when you reboot. However, you can establish a baseline for Ethernet statistics by setting a group of reference counters to zero.

To set a baseline for Fast Ethernet interfaces, issue the baseline interface FastEthernet command:

host1#baseline interface fastEthernet

To set a baseline for Gigabit Ethernet interfaces, issue the baseline interface FastEthernet command:

host1#baseline interface gigabitEthernet

To set a baseline for 10-Gigabit Ethernet interfaces, issue the baseline interface FastEthernet command:

host1#baseline interface tenGigabitEthernet

Use the delta keyword with the show interfaces fastEthernet, the show interfaces gigabitEthernet, or the show interfaces tenGigabitEthernet command to display baselined statistics.
