Hello, the following event script triggers if the route 0.0.0.0 is removed from the routing table. Is there any way to modify this to trigger the script only if the 0.0.0.0 route is still missing after a period of time i.e. 1 minute ?  The reason is I don't want the event to trigger if their is only a small routing flap that resovles itself within a few seconds.   event manager applet ResetMPIP authorization bypass event routing network 0.0.0.0/0 type remove protocol BGP ratelimit 5 action 100 syslog msg "***** Cellular modem has been power-cycled ******" action 200 cli command "enable" action 210 cli command "configure terminal" action 220 cli command "service internal" action 230 cli command "exit" action 300 cli command "test cellular 0/0/0 modem-power-cycle" ...

Hello, I am seeing a lot of fragmented UDP 17 packets in a Wireshark sniff of incoming traffic from a Cisco 4900 switch (firmware 122-53.SG10) However when I run the command 'sh ip traffic' on the switch, the fragmentation statistics look empty.

Hello, we have a large amount of Google Chrome users. I am starting to hear the odd complaint about slow connections to some sites on the internet. As a test I disabled the QUIC protocol (UDP 443) in the web browsers at one site, and the complaints stopped. In addition we also block QUIC on our firewall. So it would seem that browsers were failing to communicate via QUIC and then either stalling or taking too long to revert to TCP 443.   Are any other of you network engineers seeing the same sort of problem ? - I was considering disabling QUIC in all Chrome browsers company-wide.  ...
