| Omschrijving | Multilayer Switch, 4 Gigabit uplink + 48 10/100BASE-T IPv4 and
IPv6, -48Vdc PS
|
| | 1U form factor allows optimum use of rack space and thus higherdensity of ports per rack. Front-to-back cooling for optimum rack/cabinet airflow. Operating temperature extends to 50C (122F).Policy based QoS ensures performance of delay-sensitiveapplications. Internal dual hot-swappable AC or DC load-sharingpower supplies remove the need for an expensive, rack-space-wastingRPS.
Features:
- Huge capabilities and flexibility compressed into 1U formfactor
- Front to back cooling for optimum rack/cabinet airflow
- Operating temperature extends to 50C (122F)
- Internal dual hot-swappable AC or DC load-sharing powersupplies remove the need for an expensive and rack space wastingRPS
- Layer 2 and 3 IPv4 and IPv6 routing all at wirespeed
- Built from a 37.6Gbps switch fabric yielding 13.1Mppsperformance
- Provides 256K Layer 3 address table entries
- Supports full 4096 VLANs with VLAN double tagging
- Private VLANs
- Supports 4096 Layer 3 interfaces
- Fixed ports 48x 10/100T on the front panel
- 4x SFP (Small Form Pluggable) uplinks on the frontpanel
- A Compact Flash port, accessible via the front panel, whichconveniently enables configurations and other information to bestored for backup, and for use on other switches
- Asynchronous management port available via the front panel forease of access
- SFP uplink ports will support any combination of 1000T, 1000SX,1000LX SFP or 1000ZX SFP
- Full environmental monitoring, with alerts to network managerin case of failure of any PSU or FAN
- Extensive wirespeed traffic classification
- Policy-based QoS features
- Min/max bandwidth control with bandwidth slice resolution downto 1kbps on ingress
- Buffered max bandwidth control at egress on all ports, and oneach of 8 egress queues per port
- Three drop precedence (green, yellow and red) per priorityqueue on egress for improved TCP-IP bandwidth limitingperformance
- Low latency for voice and multi-media support
- Web-based management with GUI3
- SNMP with extensive MIB support
- Advanced routing protocols OSPF, BGP4, IS-IS, RIP and RIPv2,DVMRP, PIM-SM, PIM-DM
- Port trunking
- Port mirroring
- Wirespeed multicasting
- Secure SSH capability on management and access

| Omschrijving |
10/100 x 48 ports managed Fast Ethernet Layer 3 Switch w/ 4 SFP expansion bays
The AT-8948 is one of the most advanced Fast Ethernet switches available. An upgrade path to IPv6, fine service provisioning, and QoS features make the 8948 a smart choice when your network needs comprehensive control over service quality and bandwidth.
The AT-8948 supports dual hot-swappable power supplies and the front-to-back airflow optimizes switch cooling. You can add a hardware-based IPv6 card for added line rate support. The AT-8948 meets the performance and IPv6 transition needs of your network. |
