Pls guide for the configuration for topology attached

Dear Netpros,

I am attaching a Rough Topology Dia.

There are around 30 Vlans on Netwrok.

Netwrok should be fully Redundant and managable.

Can you suggest me the configuration guide ?

Should we use Vlan creation and intervlan routing on Core layer or on Distribution layer ?

How ?

Pls reply ......

Re: Pls guide for the configuration for topology attached

i suggest :

c4500 will be distribution and core layer. here you will define VLANs (VTP server) and SVI , routing, ACL,..., STP (mst mode)

c3560 will be access layer (L2 only). (VTP clients) here you will attribute ports to VLANS.

of course uplinks will be trunks

a typical config can be found here:

other usefull commands are in the same web page

Re: Pls guide for the configuration for topology attached

Dear ohassairi,

Thanks.

I have one more confusion.

How to configure any vlan i.e vlan 5 Ip address if TWO SUP V with 2 10 GE card in one 4510R core sw and with high Availability are there?

e.g

Int Vlan 5

ip address 172.120.25.101 255.255.255.0 alt 172.120.25.102 255.255.255.0

or

Pls suggest.

Pls give me the sample config for one vlan 5.

Regards,

L2 switch: 2975 or 3750

L3 switch: If you want 2 x 10 Gb and SFP, look at WS-C3560E-12D or -12SD.

Re: Pls guide for the configuration for topology attached

Dear Dipesh ,

you can have your VLAN splitted across between your core Switches ( 15+15) by enabling HSRP among the VLAN for High Availability .

Similarly PVST on Access layer to ensure uplink between two core switches ,

look the sample config attached .

Re: Pls guide for the configuration for topology attached

the second SUP in the same sw will not obtain any IP. you can consider that you have only one SUP.

u need just to define redendancy mode with some commands like:

Switch(config)# redundancy

Switch(config-red)# mode sso

for more details see:

Re: Pls guide for the configuration for topology attached

hi ohassairi,

It means that :

If I have 2 nos of Sup and config is for example :

int vlan 5

Ip address 10.2.151.5 255.255.255.0

now Active sup i will remove than automatically this Ip will be used for other SUP?

M i correct ?
