I got permission to ask one of our Cisco Enterprise technical sales people. Here is his reply on what are the differences between the 2510G-24 and the 2810-24G:
<quote> 2510 Convergence . IP multicast (data-driven IGMPv3): automatically prevents flooding of IP multicast traffic (except 2510-24) Quality of Service (QoS) . IEEE 802.1p prioritization: delivers data to devices based on the priority and type of traffic Layer 2 switching . VLAN support and tagging: support up to 64 port-based VLANs and dynamic configuration of IEEE 802.1Q VLAN tagging, providing security between workgroups . GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs . Jumbo packet support (2510G only): supports up to 9,216-byte frame size to improve performance of large data transfers 2810 Convergence . IP multicast snooping and data-driven IGMP: automatically prevents flooding of IP multicast traffic . IEEE 802.1ab LLDP discovery: advertises and receives management information from adjacent devices on a network . Per-port broadcast throttling: selectively configure broadcast control on heavy traffic port uplinks Quality of Service (QoS) . Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into 8 priority levels mapped to 4 queues . Class of Service (CoS): sets IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), L3 protocol, TCP/UDP port number, source port, and DiffServ . Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers Layer 2 switching . VLAN support and tagging: support complete IEEE 802.1Q (4,096 VLAN IDs) and 256 VLANs simultaneously . GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs . Jumbo packet support: supports up to 9,216 byte frame size to improve performance of large data transfers There are some other differences concerning security and manageability as well. </quote> Webster > -----Original Message----- > From: Andy Ognenoff [mailto:[email protected]] > Subject: RE: Advice on switch for personal lab > > Looking at the specs, there are a couple differences, but again > probably > only warrants the price difference if you actually need it. > > Throughput > 2510: up to 35.7 million pps > 2810: up to 71.4 million pps > > Switching capacity > 2510: 48 Gbps > 2810: 96 Gbps > > Maximum heat dissipation > 2510: 164 BTU/hr (173 kJ/hr) > 2810: 341 BTU/hr (360 kJ/hr) > > - Andy O. > > >-----Original Message----- > >From: Matthew W.
