In the pass few months, my users have experience Internet Drop (www, mail ect...)
and I couldn't find a solution for it.
Some users would have diff results but always the same issue. For example,
user A can ping a http://www.google.com which translates to IP and all icmp is a success. This result tells us its not a DNS issue. ICMP works but browsing to any www site and email fails.
user B cannot ping and use www/email. This is on the same cluster separated using VLANS.
I did notice I get this:
%IP_VFR-4-FRAG_TABLE_OVERFLOW: FastEthernet0/0: the fragment table has reached its maximum threshold 64 on the router logg.
I did some research and Cisco states I should enter this on the CLI "ip virtual-reassembly max-reassemblies #". I increase the max reassembly but problem is still there.
Until today, clients during diff times would still get the problem on the browser. And all not at the same time, more intermittent.
