Migrating From Cisco to Brocade

Current network config

Cisco WS-C3750G-12s-s 12 port fiber switch acts as gateway, serves as VTP server; existing vlans are only configured on the Fiber switch, this is propagated to all other Ethernet switches this is the main distribution point for all other switches on LAN


Vlan config

interface Vlan1

description Management Vlan

ip address 172.29.0.1 255.255.255.0

!

interface Vlan4

description Servers

ip address 172.29.4.1 255.255.255.0

ip helper-address 172.29.4.10

!

interface Vlan8

description Workstations

ip address 172.29.6.1 255.255.255.0

ip helper-address 172.29.4.10

!

I know that VTP is unique to Cisco but it seems that GVRP will produce similar results. Is this Correct?

In my new deployment I am replacing Cisco equipment with Brocade equivalents

TurboIron24x is replacing WS-C3750G

FastIron48 are replacing typical Catalyst Ethernet switches

My plan is to install the TurboIron in place of the WS-C3750G configuring the VLANS here, using GVRP to share VLANs thoughout network to 4 switch stacks. Am I correct in thinking this is possible?

I have started to configure the first stack and the TurboIron. I found the option to enable GVRP on the first FastIron stack, I could not find this option on the TurboIron. Am I missing something?

Lastly when configuring Vlans in our Cisco environment I would follow these steps

1) Enable Vlan

2) Name Vlan

3) Assign IP to Vlan

4) Add IP-Helper address if needed

5) Assign Vlans to desired ports

How would this process differ in a Brocade Environment?

I know this is a long question, I thank everyone in advance for taking the time to read and/or answer my question.

Re: Migrating From Cisco to Brocade

Would booting the TurboIron into L3 mode resolve some of my issues?

"sh flash" output

DR.MDF.TURBOIRON24X#sh flash

Compressed Pri Code size = 4490027, Version:04.2.00b (/foundry/FGS/os/TIS04200b.bin)

Compressed Sec Code size = 4490027, Version:04.2.00b (/foundry/FGS/os/TIS04200b.bin)

Compressed Boot-Monitor Image size = 373767, Version:04.1.00T205 (grz04100)

Code Flash Free Space = 23068672

DR.MDF.TURBOIRON24X#

My primary and secondary flash options are both "Switch" mode. Is the TurboIron L3 boot image available online?

Re: Migrating From Cisco to Brocade

Hi

     The easy part first - Yes the layer 3 code is available via the online my.brocade.com site (downloads section).  Next yes the layer 3 code is what you need for the TI24.

Next Cisco to Brocade

1) Enable Vlan

     Brocade - VLAN are enabled by default when create - but in a down state until the first port is litup

2) Name Vlan

     Brocade - you name the VLAN when you create it e.g.

                    switch(config)#vlan 33 name myvlanname

3) Assign IP to Vlan

     Brocade - switch(config)#vlan 44 name myvlanname

                    switch(config-vlan-33)#router interface ve 33

                    switch(config-vlan-33)#interface ve 33

                    switch(config-ve-33)#ip address a.b.c.d/xx

4) Add IP-Helper address if needed

                    switch(config-ve-33)#ip helper-address 1 a.b.c.d

5) Assign Vlans to desired ports

                    switch(config-vlan-33)#tag ethernet slot/port      (like switchport mode trunk)

                    switch(config-vlan-33)#untag ethernet slot/port   (like switchport mode access)

see http://community.brocade.com/docs/DOC-2347 for a good guide to the different commands

Then last part, yes I think GVRP will do what you need - though I have never used it myself - but a quick reads say yep should work for you.

Thanks

Michael.
