Can an S series switches be used without a license
Basic functions of S series (except the S1700) and E series switches can be used without a license. Some features cannot be used without a license, such as SVF and traffic distribution. To use these features, apply for licenses for them.

Whether universal line boards can be used in slave subracks
No. Universal line boards can be used only in independent subracks, but not in the master or slave subracks.

How are VRRP packets of an S series switch sent in a super-VLAN
For S series switches (except the S1700), you are not advised to create a VRRP group on the corresponding VLANIF interface for a super-VLAN. If such a VRRP group has been created, the total number of VLANs (including common VLANs, super-VLANs, and sub-VLANs) in the VRRP group cannot exceed 256 to minimize impact on host performance. By default, if a VRRP group is configured for a super-VLAN, the master switch sends VRRP Advertisement packets to the super-VLAN's sub-VLAN that is in Up state and has the smallest VLAN ID among all the sub-VLANs. You can run a related command to configure VRRP Advertisement packets to be sent in a specified sub-VLAN. This prevents VRRP Advertisement packets from being broadcast in all sub-VLANs, reducing network bandwidth consumption. The configuration procedure is as follows: 1. Run the system-view command to enter the system view. 2. Run the interface vlanif vlan-id command to enter the VLANIF interface view. 3. Run the vrrp advertise send-mode { sub-vlan-id | all } command to configure a mode in which the master switch sends VRRP Advertisement packets in a super-VLAN. - sub-vlan-id: specifies the ID of a sub-VLAN where the master switch sends VRRP Advertisement packets. - all: indicates that the master switch sends VRRP Advertisement packets to all sub-VLANs in a super-VLAN. Note: The parameter all is not recommended. If all is configured, a super-VLAN broadcasts a VRRP Advertisement packet to all its sub-VLANs, which increases bandwidth usage.
