HiI have a network with two 6509s, 720-3BXL in the core of it. The 6509s are connected to each other over a trunk with all VLANs allowed over it. Down the line there are top of the rack switches, each connected to both 6509s over trunks. Only VLANs c...
HiI have asked this question before, but as I have not get far with it I am going to try to be more specific this time.I have a server that needs to do an outbound connection to a mail server. The connection has to be initiated to port 26, that then ...
HiI am trying to configure the ACE to NAT both IP and port based on the source IP and destination port. For example all traffic from an internal IP going to any destination to port 26 should be Natted to an external IP and the port 26 changed to 25. ...
Hi I have two 6506s with SUP2 on them. There has been a problem there with maxing out BGP routes on both switches, which was resolved by quite aggressively filtering incoming updates from our transit. Now I have come across a rather strange phenomeno...

Another questionCould anyone explain please where the leak may be happening if the core switch sends traffic out of one VLAN and I see it hitting an access switch on another VLAN. There is one cable between the core switch and the access switch and o...
Giuseppeit is 4 hours everywhere.Still what can cause a 65009 to do very regular ARP broadcasts? I am going to shut one of the boxes down to try what you suggested. I will have to do it next week though, so may not have any updates till then.Thank yo...
Well I am assuming the ARP timeout is set to 4 hours as there is nothing about ARP timout in the sh ip int VLAN blah blah I can see.sh ip int vlan 303Vlan303 is up, line protocol is up Internet address is x.x.x.x/24 Broadcast address is 255.255.255...
Yepdone wireshark on all VLANs. It seems to be the two core switches that generate all this traffic. I should probably say again that it is the management VLAN that gets hit by traffic destined to other VLANs, not any other VLAns.We have VM Ware syst...
