max number of hops? 1

[dvtestguy]

I have 6 of Linksys devices in a lab (SRW248G4, 48-port 10/100 + 4-Port Gigabit Switch) all supporting IP Management in one Vlan (10) for 200 devices that require IP's on subnet 10.10.10.x

My question...All are daisy chained via one gigabit port, and noticed I'm seeing some collisions and slow responses on a few of these managed hubs. I'm guessing that I've exceeded the Class I/II hops?

Thanks...

dvtestguy,

You might want to list what equipment you are using and exactly how you have it setup. Are you using hubs? Or are you using switches?

It really might be a mute point depending on the Linksys "hub" if you are really using hubs, I say that because about 6 years ago at a Cisco convention Fluke did a demo of Linksys, Netgear and D-Link "hubs" and proved to us that these things sold as a SOHO "hub" were switches, they just packaged the switches as "hubs" and did not include software and as switches and included software but they were exactly the same - layer 2 switches!!!

Are you saying that you are running 200 devices through a 4 port Linksys Gig switch??? What kind of traffic and exactly what are these devices?

If you have ANY king of traffic I would think the trouble is 200 devices trying to use a 4 port SOHO device. I know that Cisco even lists that for the Cisco SOHO routers it is best to have between 20 and 50 users depending on traffic. I could just imagine for a 4 port switch designed for home use you would be lucky to get about 20 users!

I have about 200 to 225 users at work and I am using a Cisco CAT 4006 switch with 4 GIG uplinks to the rest of the network, I could not think of running any kind of traffic through a 4 port Linksys ANYTHING !!!

Just some thoughts

CiscoGuy33,

All devices are SRW248G4 Gigabit Switches.

http://www.cisco.com/en/US/products/ps9992/index.html

I have a gigabit port on a C6506 configured with Vlan 10 for IP management.

interface GigabitEthernet3/2
description Linksys 1 G1
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 10
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk

C6506 (Port 3/2) > Linksys 1 (Port G1) >
Linksys 1 (Port G2) > Linksys 2 (Port G1) >
Linksys 2 (Port G2) > Linksys 3 (Port G1) >
Linksys 3 (Port G2) > Linksys 4 (Port G1) >
Linksys 4 (Port G2) > Linksys 5 (Port G1) >
Linksys 5 (Port G2) > Linksys 6 (Port G1) >

Linksys Vlan Managment on G1/G2 ports are on Vlan 10.

dvtestguy,

I would think that Linksys 1 and 2 are getting killed with traffic with this setup - EVERYTHING is cascading to them up the chain!!

If you don't have 6 free GIG ports on the C6506 then I think (IMHO) this would be a little better than cascading them:

                            Port G2---G1 L2 G2---G1 L5
C6506 Port 3/2---Port G1 L1 Port G3---G1 L3 G2---G1 L6
                            Port G4---G1 L4


I would rather see something like this even:

                                    Port G2---G1 L1 
C6506 Port 3/2---Port G1 New Switch Port G3---G1 L2 
                          8 port    Port G4---G1 L3
                                    Port G5---G1 L4
                                    Port G6---G1 L5
                                    Port G7---G1 L6

I hope this helps!

I'll give this a shot. Pending I have enough ports on the 6506
