1.1.10 GARP Switch Operation
Some or all ports on the switch may be activated to operate under the Generic Attribute
Registration Protocol (GARP) applications, GARP VLAN Registration Protocol (GVRP) and/or
GARP Multicast Registration Protocol (GMRP).
GARP is a protocol, or set of rules, that outlines a mechanism for propagating the port state and/or
user information throughout a bridged LAN to keep track of users and VLANs on the network
fabric. MAC bridges and end users alike can take part in the registration and de-registration of
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 SmartSwitch Series 6H202, 6H203, 6H252, 6H253, 6H258, 6H259,
6H262, 6E233, and 6E253 Local Management User’s Guide.
1.1.11 802.1 Port Priority
IEEE 802.1 port priority is incorporated in the IEEE 802.1D standard. It is used to assign a default
priority to the frames received without priority information in their tag header, to map prioritized
frames to the appropriate transmit queues, and to prioritize frames according to protocol type.
1.1.12 Management
Management of the 6E233-49 SmartSwitch module and 6C105 chassis is accomplished using
Local Management application or remote SNMP management stations. Local Management is
accessible through the RS232 COM port on the front panel using a local VT100 terminal, or a
remote VT100 terminal via a modem connection, and in-band via a Telnet connection. In-band
remote management is possible through any SNMP compliant Network Management Software.
Local Management, as described in this user’s guide, provides the ability to manage the 6E233-49.
Local Management information for non-Ethernet HSIMs or VHSIMs is included in their
respective user’s guide. For details on how to get manuals, refer to the Related Manuals section in
the About This Guide section.
1.1.13 Switching Options
The 6E233-49 SmartSwitch provides 802.1Q switching or SecureFast Switching Virtual Network
Services between all of the front panel interfaces including any optional HSIMs. In the 802.1Q
mode (the default mode of operation), the switch functions as an 802.1D switch until VLANs are
configured. SecureFast switching and IEEE 802.1Q switching allow migration to Virtual Network
technologies without requiring the replacement of existing equipment.
