See the original at +<a href=http://nitrous.digex.net>http://nitrous.digex.net</a>. +</ul> +</p> +<p> +<UL> +<li>Some items are not implemented for the junipers/foundrys yet (so, as i get + to it) or no equivalent command exists. +<li>If there is something which you feel is missing, feel free to ask + and/or send comments to <a href=mailto:rancid@shrubbery.net> + rancid@shrubbery.net</a>. No guarantees.</li> +<li>Only one query per router allowed at any given time. This is to avoid + resource deprivation on the looking glass host or the router. The + looking glass will attempt to serialize queries.</li> +<li>The looking glass will ping a router prior to querying it to avoid + trying to query routers which are down or otherwise inaccessible.</li> +<li>Login failures can be intermittent or permanent, either due to the + router being inaccessible from the looking glass machine, + or authorization failure(s). Contact your local network engineering + folks to resolve login failures.</li> +<li>Queries followed by <something> require an argument(s) in the text + window below the query list. Some queries take optional arguments + denoted by [something]. Multiple arguments should be separated by a + space.</li> +<li>Note that output from certain queries is cached by the server and may + be slightly out of date. These queries will be noted as such in the + output. This is limited to queries which could produce lots of output, + such as 'sh ip bgp dampened-paths'.</li> +<li>Note that some queries have potential to produce great load on the router + and produce lots of output, such as 'sh ip bgp' or 'sh ip bgp reg '^3561'. + The looking glass attempts to deny such commands.</li> +</ul> +<p> +Some useful hints: +<UL> +<li>Show interfaces can take arguments other than an interface name, assuming + the router is running an O/S version with the capability. For example; a + cisco can take 'descriptions' or 'brief' and 'terse' for the juniper. </li> +<li>Show ip bgp neighbor can take additional arguments (if configured to allow + it), such as 'advertised routes', 'flap-statistics', 'received-routes', + and 'routes'. The argument will be converted for the platform.</li> +</ul> + +</body> +</html> |
