  1. AT-86xx Cost Effective L3 Switch

  2. AT-8600 SERIESLayer 3 Fast Ethernet Switches • AT-8624T/2M • 24 x 10/100BASE-T + 2 x Uplink Module Bays • Layer 3 switch with Layer 2/3/4+ intelligence • AT-8648T/2SP • 48 x 10/100BASE-T + 2 x SFP ports • AT-8624POE • 24 x 10/100BASE-T with PoE + 2 x Uplink Module Bays

  3. Hardware • Based on 85xx hardware and ASCI BCM5645 • 32MB RAM • 8MB Flash Memory • 200MHz PowerPC CPU - Motorola • 255 VLANs • 8K MAC Addresses

  4. Performance • AT-8624T/2M 11.8 Gbps switching fabric, • 6.6 Mpps forwarding rate • AT-8648T/2SP 23.6 Gbps switching fabric, • 10.1 Mpps forwarding rate • AT-8624POE 11.8 Gbps switching fabric, • 6.6 Mpps forwarding rate • Latency: • 40 microseconds latency between 10Mbps ports • 11 microseconds latency between 100Mbps ports • 4 microseconds latency between 1000Mbps ports • Switching • 14,880pps for 10Mbps Ethernet • 148,800pps for 100Mbps Fast Ethernet • 1,488,000pps for 1000Mbps Gigabit Ethernet

  5. Comprehensive Layer 2 Support • 802.1Q port based VLAN (tagged) • Up to 255 VLANs • Static and Dynamic VLANs (GVRP, GARP) • VLAN Relay • Private VLAN • 8,000 MAC Addresses • Port security (MAC-based)

  6. Redundancy • Port Trunking with Link aggregation (802.3ad static) (LACP) • STP/RSTP/MSTP (IEEE 802.1s) • Redundant Power Supply (RPS) option

  7. Layer 3 Features • IP RIPv1/v2 • OSPF v2 • VRRP • BootP relay • DNS relay

  8. Multicast • IGMP • IGMP snooping • IGMP proxy • MVR • Broadcast forwarding • Static multicast forwarding

  9. Quality of Service Features • 802.1p (CoS) • IP TOS/DiffServ • 4 Queues per egress port (PQ/WRR/Bounded Delay WRR) • Re-mapping CoS/ToS/DiffServ for ingress/egress • QoS classifiers based on any of the following: • Port or VLAN • IP Source / Destination Address • TCP Source / Destination Port, Flag • UDP Source / Destination Port • Layer 4 protocol (ICMP, IGMP etc.) • IPX Destination Address, Source / Destination • Socket, Packet type • MAC Source / Destination Address • Up to three 16-bit words inside the first 64 bytes of a packet

  10. Security • SSH and SSL for management • TACACS/TACACS+/RADIUS • 802.1x port based access security • Layer 2/3/4+ filters (permit or deny traffic) • Storm control • Remote Security Officer • MD5 authentication • PKI • User Authentication Database

  11. Web based GUI HTTP client/server Email client/SMTP CLI IP multihoming SNMPv3 Trigger Facility NTPv3 RMON Stacking (non-proprietary) Editor Mail Configurable debugging Login banner Release/patch licences LOAD via ASYN,TFTP, HTTP, LDAP Logging Scripting Trap MIB Multiple software image storage Management

  12. Rate Limiting • EGRESSLIMIT specifies the maximum bandwidth for traffic egressing the specified port(s), in kbps (10/100 Mbps ports) or Mbps (Gigabit ports) • For 10/100 Mbps ports the input value (1000..127000) in kbps is rounded up to the nearest 1000 (or 1 Mbps) • For Gigabit ports the input value (8..1016) in Mbps is rounded up to the nearest 8 Mbps

  13. Competitive Overview • Cisco 3550-24-SMI • Price – expensive • Routing – requires additional licence (EMI) for OSPF • Security – requires additional licence (EMI) for extended ACLs • 3Com 3226 • Routing – RIP only, essentially a Layer 2 switch • Resiliency – no RSTP or MSTP (802.1s) • QoS – basic classifiers only, not full Layer 2/3/4+ support • Security – basic ACLs only • Management – no support for secure management SNMPv3 • HP Procurve 2626 • Routing – Layer 2 switch • Resiliency – no MSTP (802.1s) • QoS – 802.1p only • Bandwidth control – not supported • Multicast – not supported • Reliability – no redundant power supply option • VLANs – limited to 30
