This chapter introduces the 2E253-49R SmartSwitch 2200 device and provides information about how to obtain additional support from Cabletron Systems. Depending on the firmware version used in the 2E253-49R, some features described in this document may not be supported. Refer to the Release Notes shipped with the 2E253-49R to determine which features are supported.
Virtual Local Area Networks (VLANs) and control the flow of frames associated with each VLAN according to priority and Ether type. Detailed information about VLANs is provided in the Cabletron Systems SmartSwitch Series 2E253, 2H252, 2H253, and 2H258 Local Management User’s Guide.
1.1.3 Standard/Full Duplex Auto-Negotiation Ports 1 through 48 on the 2E253-49R have the ability to auto-negotiate the port mode of operation (standard [half duplex] or full duplex) between two devices according to the 802.3x standard. Full duplex mode is the default mode of operation for each port. During Auto-Negotiation, two devices automatically exchange information “telling”...
History groups are enabled on all ports by default. Cabletron Systems RMON Actions is a vendor-specific extension of RMON and provides the ability to set an “Action” on any SNMP MIB variable. The Action can be triggered by any RMON Event and/or Alarm.
1.1.9 Traffic Rate Limiting The Rate Limiting feature enables the SmartSwitch device to have control over traffic rates on a per-port, per-priority basis. The network administrator can configure a rate limit (from 100 kbps to 1 Gbps) for a given port with an associated list of IEEE 802.1p priorities (which can include one, some, or all of the eight priority levels defined in 802.1p).
GARP attributes such as VLAN and multicast group membership. For more details on how GVRP and GMRP handle frames under GARP, and how to configure the switch ports to take advantage of this operation, refer to the Cabletron Systems SmartSwitch Series 2E253, 2H252, 2H253, and 2H258 Local Management User’s Guide.
