How many member interfaces does an aggregation group of the switch support

18

An aggregation group of the switch supports a maximum of eight member interfaces.
NOTE: An aggregation group of the S2700SI supports a maximum of four member interfaces.

Do member interfaces of a link aggregation group require contiguous interface numbers
For S series switches (except the S1700), the member interface numbers of a link aggregation group are not necessarily contiguous. The configuration command determines whether member interface numbers are contiguous: 1. If you run the trunkport command to configure link aggregation, you must specify contiguous interface numbers. 2. If you run the interface eth-trunk command to create a link aggregation group, and then add member interfaces to the group in the interface view, the member interfaces can have discontiguous numbers.

How many stack's members does support on S series switches
1.The number of S2700EI, S2710SI, or S2750EI used to set up a stack is recommended to be 2 to 5. 2.The S2720EI has only one model, S2720-28TP-EI-AC, in V200R006C10, V200R009C00, and V200R010C00. The S2720-28TP-EI-AC cannot be upgraded to V200R011C00 and later versions. The number of S2720-28TP-EI-ACs used to set up a stack is recommended to be 2 to 5. In V200R011C10 and later versions, the number of S2720EIs used to set up a stack is recommended to be 2 to 9. 3.The number of S3700, S5700EI, S5700SI, S5700LI, S5700S-LI, S5700HI, S5710HI, S5710-C-LI, S5710-X-LI, S5710EI, or S6700EI used to set up a stack is recommended to be 2 to 5. 4.The number of S5720HI, S5730HI, S5720EI, S5720LI, S5720S-LI, S5720SI, S5720S-SI, S5720I-SI, S5730SI, S5730S-EI, S6720HI, S6720EI, S6720S-EI, S6720SI, S6720S-SI, S6720LI, or S6720S-LI used to set up a stack is recommended to be 2 to 9.

How to check member interfaces in a port group
You can run the display port-group [ all | port-group-name ] command to check member interfaces in a permanent port group. The port group function allows you to configure interfaces in a batch. However, the device does not support query or saving of the port group configuration. You can run the display this command in the interface view of a member interface to check the configuration that takes effect on the interface. # Check member interfaces in all permanent port groups. display port-group all Portgroup: 1 GigabitEthernet0/0/1 GigabitEthernet0/0/2 GigabitEthernet0/0/3 Portgroup: 2 GigabitEthernet0/0/4 GigabitEthernet0/0/5 GigabitEthernet0/0/6

How many VTY user interfaces does a switch support
By default, a switch allows a maximum of five VTY users at a time. You can set the maximum number of VTY users allowed using the user-interface maximum-vty command. This maximum number can be set to 15 at most (a maximum of 15 VTY users allowed). When the maximum number of VTY user interfaces is set to 0, no user (even NMS user) can log in to the switch.
