 | When you use an HTTPS connection in the Microsoft Internet Explorer browser to save a report from this page in the J-Web interface, the error message "Internet Explorer was not able to open the Internet site" is displayed. This problem occurs because the Cache-Control: no cache HTTP header is added on the server side and Internet Explorer does not allow you to download the encrypted file with the Cache-Control: no cache HTTP header set in the response from the server. As a workaround, refer to Microsoft Knowledge Base article 323308, which is available at this URL: http://support.microsoft.com/kb/323308. Also, you can alternatively use HTTP in the Internet Explorer browser or use HTTPS in the Mozilla Firefox browser to save a file from this page. |
Table 239 describes the different filters, their functions, and the associated actions.
Table 240 summarizes key output fields in the routing information display.

Receive protocol | Specifies the dynamic routing protocol using which the routing information was received through a particular neighbor. | Enter the routing protocol. |
Best route | Specifies only the best route available. | Select the view details of the best route. |

Table 240: Summary of Key Routing Information Output Fields
Field | Values | Additional Information |
|---|---|---|
Static Route Addresses | The list of static route addresses. | – |
Protocol | Protocol from which the route was learned: Static, Direct, Local, or the name of a particular protocol. | – |
Preference | The preference is the individual preference value for the route. | The route preference is used as one of the route selection criteria. |
Next-Hop | Network Layer address of the directly reachable neighboring system (if applicable) and the interface used to reach it. | If a next hop is listed as Discard, all traffic with that destination address is discarded rather than routed. This value generally means that the route is a static route for which the discard attribute has been set. If a next hop is listed as Reject, all traffic with that destination address is rejected. This value generally means that the address is unreachable. For example, if the address is a configured interface address and the interface is unavailable, traffic bound for that address is rejected. If a next hop is listed as Local, the destination is an address on the host (either the loopback address or Ethernet management port 0 address, for example). |
Age | How long the route has been active. | – |
State | Flags for this route. | There are many possible flags. |
AS Path | AS path through which the route was learned. The letters of the AS path indicate the path origin:
| – |
