Clustered Switch Management

I've setup a total of 5 switch in a cluster and wanted to try to managed it using web.

But whenever i http to the switch IP, i can't see any option for CSM, I just got the normal page for a single switch.

Anything that i need to configure??

Re: Clustered Switch Management

I would recommend you to use CNA (Cisco Network Assistant) than HTTP as it has got its own vulnerabilities.

For CNA you need to enable SNMP and get level 15 username and password. If you want to make changes into the switch through CNA then you need to create Read/Write SNMP community.

You can manage your switch cluster easily with CNA.

Re: Clustered Switch Management

i thought i can use CMS to managed that, which is easier for users..

btw, if i've a cluster of 5 switches, and the cluster is connected to the same core switch via SFP on the commander switch and another fiber link via the last member of the cluster switch, will that create a loop in this topology??

can i create an etherchannel between there 2 fiber link which is connected to 2 different switch in a cluster??

Re: Clustered Switch Management

Hi,

Which model number of switches you have. Do you have the related HTTP and other CMS files/directory in the switch flash. You need the IOS image with .tar extension which has all the related HTTP/CMS files to manage the switches via WEB and CMS. You also need Java plugin on your PC.

You can also use CNA to manage you all the switches. Please find a link below on CNA datasheet which has a list of all the supported Devices.

If you have a cluster of 5 connected switches and they are connected as you discussed above, yes it will form a STP loop and one link will be automatically in blocked state.

If you have 3750 switches with 2 fiber links which are connected to 2 different switch, then you can create an etherchannel. Its is not possible on other switches.

HTH, Please rate if it does.

Re: Clustered Switch Management

but, the 5 connected clustered switches connected to the same core switch.

and the core switch see the switches as different switch, so does it still create a loop?

Re: Clustered Switch Management

Understand the physical connectivity.I think it will be something like this

Core Switch Link 1--Sw1-S2-S3-S4-S5---Core switch Link 2

If yes, then this is a loop.If you disconnect any cable in the middle then it will not be a loop.

Re: Clustered Switch Management

yes, the physical connectivity is correct as shown.

but, i've spanning-tree enabled, it shouldnt create a loop, right?

i still dont understand, coz the core switch sees Sw1 and Sw5 as different switch, and y there will be a loop?

Re: Clustered Switch Management

Loop will not be there, as we have the STP working in the scenario. The physical connectivity will create the loop but as we have STP working here, it will block one of the port and hence no loop will occur. If you check "show spanning-tree " on the switch, it should list you which port is in blocking state and which one is in forwrading state.

HTH, Please rate if it does.

Re: Clustered Switch Management

i did show spanning-tree..and there is no blocked ports at all on all switches..
