I'm having a strange problem where i don't know further.
We have 5 Summit Switches (X460-24p/t & X460-48p/t) in a ring topology (with EAPS). Everything is working fine but now we saw that loading a certain website won't work.
The Setup is like this:
... SW3 <--> SW4 <--> SW5 <--> SW6 <--> Firewall <--> Internet
The website is working on SW5 and SW6 without problems. But SW4 and everything below won't load this certain page. With wireshark I saw, that the SYN Package is travelling to the website. The SYN ACK page is coming back and leaving SW5. But on SW4 i can't see the package arriving. It seems that the SW4 is dropping the package due to a ip restriction.
There are no ACL's configured on the SW4. ip-security source-ip-lockdown isn't configured either. So at the moment I have no idea what the matter is. Does anyone has a idea which would be helpful?
Thanks in advance
