We have a stack of 6 AT - 8326GB switches (which we can access as a single hostname "switch4"), and a newer AT-80000S ("switch0").
switch0 was originally also an 8326GB, but was replaced with the AT-80000S under our maintenance contract when it failed.
I used to access both switch4 and switch0 via telnet or http interfaces. In particular what I want to do is to access PROGRAMMATICALLY the information which tell me which MAC address is attached to which slot in the switch. I do this (a)periodically for monitoring, or to update a database.
I had originally both a crontab shell script (for mysql database updating) and a CGI shell script (for realtime monitoring). They used to interrogate the switches running a telnet session under "expect".
This worked nicely for both switches, and still does for switch4. But the NEW switch0 has a totally different telnet interface and I cannot find where the slot (port) to MAC address info is kept now !!!
Recently I converted the realtime monitoring tool to a java class. This is done opening an URL connection to
URL url = new URL("http://switch4/fdbport.htm?port="+port+"&deviceno="+hubdev) ; URLConnection uc = url.openConnection(); uc.setRequestProperty ("Authorization", "Basic " + encoding);
where "encoding" is a way to store user/password.
Essentially for switch4 I can connect to the web page which gives me the MAC-to-port mapping and parse it.
Old switch0 failed while I was developing the java tool, so I had no opportunity to try it.
But also the web interface of the new switch0 is TOTALLY DIFFERENT from the old one. HOWEVER I located a page Layer2->MAC address -> set radio button "view dynamic" and click "view", which gives me the right info. I can MANUALLY save the HTML output and e.g. use awk to parse the info I want. I already have such awk script !
But I wanted to do this programmatically. I thought to start with the crontab and CGI, and replace the expect/telnet arrangement with a wget to the new web page.
But the point is : which URL should I use ? I tried with (using appropriate credentials) http://switch0/FwdDb/bridg_frdData_Query_Address_m.htm?mac_filter=Dynamic which looks to be the ACTION of the html form, with the only non-default and non-hidden argument set. But the web page I get in return does not contain the info I want. If I look at the "page info" address I see an URL with a much contrived calling sequence with lots of funny characters probably requiring URL encoding.
Any idea of the proper URL to use ?
If I get it, I could also use it in java and rewrite the parsing code from awk to java.
