How to connect the cisco catalyst switch to Siemens scalance x208 switch

[GMahendra]

Dear Team,

Is it possible to connect cisco catalyst switch with industrial Ethernet scalance x208 switch ? if yes then please let me know the configuration on catalyst switch of port where industrial Ethernet scalance x208 we can connect.  Is it on access port or trunk port?

Hello Mahendra,

for connections with third party switches you may need to use the interface commands

int gi1/0/1

switchport nonegotiate

switchport mode trunk

! sometimes you may need

DTP is Cisco proprietary and the first command disables it, then with switchport mode trunk you configure the Cisco side to be a trunk that is typically used for inter switch links

Hope to help

Dear Larosa,

Is Cisco catalyst compatible with Siemens scalance x208 switch for connectivity?

Hello Mahendra,

according to the Siemens datasheet

https://support.industry.siemens.com/cs/products/6gk5208-0ba10-2aa3/scalance-x208?pid=501190&mlfb=6GK5208-0BA10-2AA3&mfn=ps&lc=en-DK

the scalance has 8 10/100 FE ports RJ45.

You should be able to connect using a giga port RJ45.

You can eventually try to add

interface gi1/0/1

speed 100

duplex full

if the link does not come up when relying on auto negotiation (to be preferred try first without the speed and duplex commands)

Hope to help
