I have a application server network that has a Cisco 3550 used for inter-vlan and policy routing.
Please see the figure from the link below.
The requirements in the network are
1. vlan 1 can access vlan 88 and vlan 97.
2. vlan 88 and vlan 97 must use their own dedicated gateway to access internet.
I have 3 MB upload and download bandwidth for every internet connection. Vlan 97 and Vlan 88 have exactly the same configuration except Vlan 88’s PIX also handles 10 remote access VPN clients.
My main problem here is that the upload speed of Vlan 88 is decreased considerably after switch 3550. It goes down from average 2500kbps to less than 900kbps constantly. The download bandwidth is always above 2200kbps.
However, Vlan 97 does not have this problem!
The only difference I can think of is the Cisco remote access VPN clients in Vlan 88. There are about 10 computers access the network by VPN client but can that cause such considerable loss of bandwidth? If so, then why the bandwidth from the PIX firewall’s inside interface can reach 2400 kbps?
Please help. I will post the sh run in my next post.
