Lan Design Help needed. 500 servers and 5 switches
I need some suggestions on setting up a new lan for a customer.
They have approximately 400 systems that all need to be connected to a gigabit backbone. We have 5+ 5000 series catalyst switches to use that are populated with 24 port 10/100 modules and supervisor III w/ netflow card engines.
The systems are broken up into 2 subnets. 96.x and 104.x 255.255.248.0.
I was thinking the best way is to setup all of this is:
-Setup 96.x in one vlan, and 104.x in another vlan.
-Dedicate 1 switch as the "core" switch which will connect to the core router with a gigabit connection.
-Core switch will have 200mbs (2 x 100) (effectively 400mbs with full duplex) etherchannels to each of the 4 switches.
-Setup VTP Trunking between the switches and the core switch.
-Setup VTP Trunking between core switch and Router for inter-vlan routing. (Unless I can get a layer 3 core switch to do this instead?)
-Also if possible to setup some QOS for priortizing ssh/telnet/icmp packets.
If I setup VTP, would that allow mac address information from each switch pass through each switch without going to the router? ie, will server on switch #1, be able to get to a server on #4 by only going thru the core switch?
You can also use a RSM (RSFC) instead of an external router, that is, if you can find one. They are EOS and EOL, I believe...
Gigabit to a router is nice, but may not be entirely necessary. 100Mbps is usually enough (and less expensive). Since the SupIII with NFFC can to MLS (L3 switching), the router will have to deal with less traffic on the whole!
[toc:faq]The ProblemOn traditional switches whenever we have a trunk
interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
[toc:faq]Introduction:Netdr is a tool available on a RSP720, Sup720 or
Sup32 that allows one to capture packets on the RP or SP inband. The
netdr command can be used to capture both Tx and Rx packets in the
software switching path. This is not a substitut...
IntroductionOSPF, being a link-state protocol, allows for every router
in the network to know of every link and OSPF speaker in the entire
network. From this picture each router independently runs the Shortest
