Hi...
I need to solve a network slowness problem. First, let me tell you about
our network. All our PCs are connected to 2 X 5500 switches with RSM and
divided into 3 VLANs 1,2,3 on each swtich. Both switches are connected to
each other via trunks and HSRP configured. VLANs are routed via RSM in
5500s. By right, implementation of VLAN can increase the performance and
speed, and 5500 switch also a high end switches. But our network is very
SLOW. All parameter have been checked including the duplex type and speed
of the ports match with NIC. I suspect can it be the bottleneck of routing
process in RSM due to overwhelming packet for routing? Each 5500 are
connected about 40 PCs. How to determined the utilization of RSM ? what is
the limit?
Besides, both 5500 are connected to the company WAN via two 1700 routers.
And our network is extremely slow when accessing the WAN especially on the
Citrix traffic although we have prioritize the citrix traffic. I don't know
what is the reason? We have two links 128K, and 256K, it should be fast. I
doubt whether the bandwidth is correct or not? When I see the output of #sh
interface as shown below. Can u say that it is 256K ?
>>> Dear Friend : BW 256 Kbit is the answer
MTU 1500 bytes, BW 256 Kbit, DLY 20000 usec
>>> router is not poor but implementation cud be poor or bad.!!! check out
bandwith utilization etc.
I heard from my friend that Cisco router is poor in handling citrix and
netbios traffic, is that true?? We are using OSPF in our WAN, but RIP in
RSMs. Could the difference in routing protocol slow down the network?
