PM3380 Overview
PM3380 Hardware statistics collection supports RMON-I (nine groups), Ethernet MIB, and SNMP agent functions. All statistics registers and data structures accessible through the CMI. Supports the implementation of Spanning Tree (IEEE 802.1D) by exchanging BPDU packets on all ports.
PM3380 Key Features
- Monolithic intelligent Gigabit Ethernet Switch Port Controller
- Integrates an IEEE 802.3z-patible Gigabit MAC
- May be used alone or in bination with other devices to build 10/100 or Gigabit switches
- Supports the Gigabit EXACT™ Bus Protocol for device interconnect
- May be used alone or in bination with other device to build high density Gigabit switches
- PM3390 EXACT Bus Switch Matrix allows non-blocking expansion up to 16 Gigabit ports
- Layer 2 line rate address lookup capability for all Ethernet port configurations supported
- Store-and-forward switching using output association input buffering for efficient memory use without Head Of Line (HOL)
- Supports up to 8,000 MAC addresses
- 1022 multicast groups available. Bitmask per group defines membership
PM3380 Applications
- Programmable packet pattern matchers for identification of ARP, RARP, ICMP, and other protocol or packet types
- Control and Management Interface provides standard interface for non real-time access to data structures (such as SNMP and RMON applications)
- Customer product differentiation is enabled by applications using CMI calls to leverage EXACT system resources
- Up to 4094 IEEE 802.1Q VLAN tags with support for 4094 FIDs
- Up to 1022 active VLANs
