    CS. The SIM group is a group of switches that are managed as a single entity. The DES-3550 may take on three different roles: Commander Switch (CS) – This is a switch that has been manually configured as the controlling device for a group, and takes on the following characteristics: It has an IP Address.
  • Page 304 6. The CaS can be configured through the CS to become a MS. After configuring one switch to operate as the CS of a SIM group, additional DES-3550 switches may join the group by either an automatic method or by manually configuring the Switch to be a MS. The CS will then serve as the in band entry point for access to the MS.
