Clearing IP Fragmentation and Reassembly Statistics

Note

Clearing SYN Cookie Statistics

OL-16202-01
You can clear IP fragmentation and reassembly statistics by using the clear
interface command in Exec mode. The syntax of this command is as follows:
clear interface [vlan vlan_id]
The optional vlan_id argument is a unique identifier of an existing interface as an
integer from 2 to 4094. If you omit the vlan keyword and vlan_id argument, you
can clear fragmentation and reassembly statistics for all interfaces in the context.
For example, to clear IP fragmentation and reassembly statistics for all interfaces
in the C1 context, enter:
host1/C1# clear interface
If you configured redundancy, then you need to explicitly clear IP fragmentation
and reassembly statistics on both the active and the standby ACEs. Clearing
statistics on the active appliance alone will leave the standby appliance's statistics
at the old values.
To clear the SYN cookie statistics, use the clear syn-cookie command. To clear
SYN cookie statistics for all VLANs that are configured in the current context,
enter the command with no arguments. The syntax of this command is as follows:
clear syn-cookie [vlan number]
The optional number argument instructs the ACE to clear SYN cookie statistics
for the specified interface. Enter an integer from 2 to 2024.
For example, to clear SYN cookie statistics for VLAN 100, enter:
host1/C1# clear syn-cookie vlan 100
