Cisco 6500 Management ip address Configuration

[Subin Kallidumpil]

Hi Team,

I would like to configure a Management ip address on 6500 by giving ip to the SVI. Following is the configuration done

1) int vlan X

    ip address 10.1.1.1 255.255.255.0

    no shut

However i am not able to reach this Switch IP from other subnet's. for ex:- 192.168.1.0/24.

What next configuration should be done, in order to make this work. I dnt want to use any routing protocol.

Regards

Subin

Hello Subin,

However i  am not able to reach this Switch IP from other subnet's. for ex:-  192.168.1.0/24

Communication between the 10.1.1.0/24 and 192.168.1.0/24 network is accomplished through routers or multilayer switches - in any case, routing is needed to reach one network from the other. The network 10.1.1.0/24 must be advertised in routing protocols so that all routers know about its presence and location - or you must set up the routing manually. The same fact goes for 192.168.1.0/24.

Your 6500 must know how to reach the 192.168.1.0/24 network. If it configured for routing, this network either must be learned via a dynamic routing protocol or it must be added to the routing table manually using the ip route command. If the 6500 is not configured for routing, you must configure a default gateway using the ip default-gateway command. The same fact goes for stations in 192.168.1.0/24.

I know that I've given you only a very schematic answer with no exact details but they depend very much on how your network looks like. Perhaps a topology diagram would help.

Best regards,

Peter

Sure.. Let me explain you with the architecture

Single Switch 6500 in Core and i have 4500 Switch in access.

Users are connected to Access Switch and are part of Vlan 192.

The SVI for vlan 192 is configured on the core which is 192.168.1.1 and for managment i am using all together a different ip and differennt vlan.

Now when i ping 10.1.1.1 , from user vlan how exaclty will the core switch reply back, since for vlan x i have no default gateway configured

Hi Subin,

There is no "default gateway for VLAN". There is only a default gateway for the entire device, if that device has no routing table, or a routing table telling the device about various networks and various paths to them. In particular, for your 6500 switch, both networks 192.168.1.0/24 and 10.1.1.0/24 are directly connected so if you enable routing on your 6500, it will know about both networks automatically and will be capable of routing packets between them.

The stations in the Vlan192 should be configured with the default gateway of 192.168.1.1 (the IP on the SVI for V192). The 6500 itself should be configured using ip routing command. Afterwards, stations in Vlan192 should be able first to ping the 192.168.1.1 and then the 10.1.1.1.

Packets to 10.1.1.1 will first arrive to the 192.168.1.1 interface as this is the default gateway for the stations in Vlan192. After 6500 finds out that the destination is one of its own addresses, it will simply respond back to the station that sent the ping as that station is in a directly connected network.

Best regards,

Peter

int vlan X

    ip address 10.1.1.1 255.255.255.0

    no shut

Please add some interfaces on core Switch to vlan x and after then check vlan x ip or not.
