Stack 2x SG500X only with one cable?

[admin]

Hi everyone.

I want to stack 2 SG500X-24 on SG1 port, with one cable SFP-H10GB. Can I then use port XG2, XG3, XG4 for switch to conect GSG300-52P?
I read datasheet, but i cant find information that I can set only one port for stack.

Hi,

Thanks for contacting Cisco support community center.

Sorry for the delay in response, Kindly check with the details below and let me know in case of any further queries.

1.        Sure, you can use single SFP-H10GB cable for stacking between 2 SG500X-24.
2.         And stacking can be done in any of the or in all the combo port available for stacking. Combo Ports are XG3/S1, XG4/S2(10G) - S3, S4(5G).
3.        If you are using even any one of the combo port for stacking, it is not possible to use XG3/S1, XG4/S2 as uplink port to connect with other switch.
4.        Only XG1 and XG2 can be used as permanent uplink port.
5.        If you need 4 uplink ports you can change the switch Stack mode setting into standalone mode. In the standalone mode you can use all the XG1, XG2, XG3, and XG4 ports as uplink ports. Note: No stacking can be done while the switch in standalone mode.
6.         For your confirmation though you are connecting the XG1 or XG2(10G) port to your SG300 it is not possible to attain 10G speed as SG300 is compatible for 10G speed.
7.        Hence it is better to configure LAG between the switches if you need high bandwidth.

Thanks,

So thats mean that i cant use 1 port (sfp port) to stack and 3 port to connect o another swith, becouse stack mode in software of this unit includes at least 2 port (i can connect one of them or two), am i correct?

When i implement the LAG between 2 distributed switches, the STP will block me half conection from SG300 switch.

SG500X offer VRRP, but it also use only 1 physical connection (at the time), in my project - from acces switch. To use two physical connection at the time from SG300 switch, one for each switch SG500 i think i must stak the distribut switch and then they will be one logical switch and i can configurate STP. But i dont have enought sfp ports.

Whether there is a way to use two connection from SG300 as LAG conect to two physical SG500X switch ?

Hi,

I hope you are doing good and sorry for the delay in response, kindly check with the details below.

Ans: Sure you can use any 1 combo port for stacking, as you mentioned as per stack mode configuration you need to choose at least 2 ports for stacking but once can be used.

Note: Though only one port is used for stacking as per your setup, you can’t use other three ports as uplink to connect with other switch at the same time; you can use the other 3 ports only for stacking when the switch is in stack mode.

But as mentioned earlier if you no need of any stack you can change the switch to stand alone mode and can use the XG3/S1, XG4/S2 as uplink port to connect with other switch along with permanent uplink port XG1, XG2.

>>When i implement the LAG between 2 distributed switches, the STP will block me half conection from SG300 switch. 

Ans: I hope if you implement the LAG the STP won’t block the connection from SG300.

>>Whether there is a way to use two connection from SG300 as LAG conect to two physical SG500X switch ?

Sure, we can connect any two ports from SG300 and can connect to two physical Sg500X switches other than the stack port of the SG500X.
