Software Features for the Three-Port Gigabit Ethernet Line Card
Features
Benefits
Auto-Negotiation
A link protocol that automatically selects full-duplex operation if enabled on the
3GE-GBIC-SC(=)
3GE-GBIC-SC(=)
Flow Control (receive)
The management of transmission between two devices; 3GE-GBIC-SC supports Rx
flow control; the 3GE-GBIC-SC(=) line card Rx flow control is negotiated with the
remote end by responding to the received PAUSE frames
flow control; the 3GE-GBIC-SC(=) line card Rx flow control is negotiated with the

Precedence Setting/Mapping
Allows the IP packet to be delivered with QoS for different classes of applications
Access Control List (xACL)
Extended access control lists used to provide access control by filtering out
unwanted packets; with xACL, filtering can be done on source destination IP
addresses and transport protocols using their source and destination address; ACLs
can be up to 128 lines long

Multiprotocol Label
Switching (MPLS/Tag
Switching)
Switching (MPLS/Tag
Switching)
Uses labels, or tags, that contain forwarding information, which are attached to IP
packets by a router; 3GE-GBIC-SC(=) currently supports MPLS-P (provider)
switching only, with future releases to include traffic engineering (TE), MPLS-PE
(provider edge) QoS to support real-time voice and video as well as Service-Level
Agreements (SLAs) that guarantee bandwidth, virtual private networks (VPNs), and
CoS in network core applications

802.1Q Virtual Local-Area
Network (VLAN)
Network (VLAN)
VLANs logical subgroup within a LAN that is created via software; combines user
stations and network devices into a single unit, regardless of the physical LAN
segment; 3GE-GBIC-S(=) can support up to 1K VLANs per card and all the VLANs
can be in one port or can be divided into many ports. Over all VLAN limitation for
the box is dependent on the number of IDBs supported by the IOS. For the latest
info about the IDB limits, please refer to:
