Advanced Configuration and Management Guide

To un-suppress a specific route, enter a command such as the following:

HP9300# clear ip bgp damping 209.157.22.0 255.255.255.0

This command un-suppresses only the route(s) for network 209.157.22.0/24.

USING THE WEB MANAGEMENT INTERFACE

1.Log on to the device using a valid user name and password for read-write access. The System configuration panel is displayed.

2.Click on the plus sign next to Command in the tree view to expand the list of command options.

3.Click on the Clear link to display the Clear panel.

4.Select the checkbox next to BGP Dampening.

5.Specify the routes from which you want to remove dampening:

•To clear dampening for all routes, select the All option.

•To clear dampening for a specific route, select IP, then enter the network address and sub-net mask in the IP and Mask fields.

6.Click the Apply button to implement the change.

Clearing Diagnostic Buffers

The routing switch stores the following BGP4 diagnostic information in buffers:

•The first 400 bytes of the last packet that contained an error

•The last NOTIFICATION message either sent or received by the routing switch

To display these buffers, use options with the show ip bgp neighbors command. See “Displaying BGP4 Neighbor Information” on page 10-90.

This information can be useful if you are working with HP Technical Support to resolve a problem. The buffers do not identify the system time when the data was written to the buffer. If you want to ensure that diagnostic data in a buffer is recent, you can clear the buffers. You can clear the buffers for a specific neighbor or for all neighbors.

If you clear the buffer containing the first 400 bytes of the last packet that contained errors, all the bytes are changed to zeros. The Last Connection Reset Reason field of the BGP neighbor table also is cleared.

If you clear the buffer containing the last NOTIFICATION message sent or received, the buffer contains no data.

You can clear the buffers for all neighbors, for an individual neighbor, or for all the neighbors within a specific peer group.

USING THE CLI

To clear these buffers for neighbor 10.0.0.1, enter the following commands:

HP9300# clear ip bgp neighbor 10.0.0.1 last-packet-with-error

HP9300# clear ip bgp neighbor 10.0.0.1 notification-errors

Syntax: clear ip bgp neighbor all <ip-addr> <peer-group-name> <as-num> last-packet-with-error notification-errors

The all <ip-addr> <peer-group-name> <as-num> specifies the neighbor. The <ip-addr> parameter specifies a neighbor by its IP interface with the routing switch. The <peer-group-name> specifies all neighbors in a specific peer group. The <as-num> parameter specifies all neighbors within the specified AS. The all parameter specifies all neighbors.
