• Flexible port selection
Provides a combination of ber and copper interface modules, 100/1000BASE-X auto-speed
selection, and 10/100/1000BASE-T auto-speed detection as well as auto-duplex and MDI/
MDI-X
• Monitor link
Collects statistics on performance and errors on physical links, increasing system availability
(Comware v5 only)
• Dual-personality functionality
Includes four 10/100/1000 ports or SFP slots for optional ber connectivity, such as Gigabit-
SX, -LX, and -LH and 100-FX
• Packet storm protection
Protects against unknown broadcast, unknown multicast, or unicast storms with user-dened
thresholds
• Flow control
Provides back pressure, using standard IEEE 802.3x—reducing congestion in heavy trac
situations
Quality of service (QoS)
• IEEE 802.1p prioritization
Delivers data to devices, based on the priority and type of trac
• Class of service (CoS)
Sets the IEEE 802.1p priority tag based on the IP address, IP type of service (ToS), L3 protocol,
TCP/ user datagram protocol (UDP) port number, source port, and DiServ
• Bandwidth shaping
– Port-based rate limiting
Enabled per-port ingress/egress-enforced bandwidth increase
– Classier-based rate limiting
Uses an access control list (ACL) to enforce increased bandwidth for ingress trac on each
port
– Reduced bandwidth
Provides per-port per-queue egress-based bandwidth reduction
• Trac policing
Supports committed access rate and line rate
• Weighted random early detection (WRED)/random early detection
Delivers congestion avoidance capabilities through the use of queue management algorithms
• Powerful QoS feature
Provides support for these congestion actions: strict priority queuing, weighted round robin,
weighted fair queuing, and WRED
