I am getting information now on the ERS3500 family of switches. Interesting stuff. They are positioned for "Entry level enterprise, small branches and SME". They even have fanless models for places where they don't want a loud switch running in the open. Like classrooms, meeting rooms, under desks and home offices. No license required for stacking and they say they support hot-swapping of units in a stack. However stacking cables do not come with the switches ( that support them ) and are ordered separately. Also seem to integrate with the Avaya 8100 wireless AP's in some way. Still finding out more about them. They should be available by the end of April from distributors. They look like they will add some 48-port units down the line to the 3500 family.
- 8 x 10/100/1000Mbps + 2 SFP ports (Standalone & fanless)
- 8 x 10/100/1000 Mbps PoE+ ports + 2 SFP ports (Standalone, dual power - fanless 60W / fan 170W modes)
- 24 x 10/100/1000Mbps with 4 shared SFP ports + 2 SFP / 2.5G rear ports
- 24 x 10/100/1000Mbps PoE+ ports with 4 shared SFP ports + 2 SFP / 2.5G rear ports (PoE budget 370W)
- 24 x 10/100Mbps + 2 Combo 10/100/1000 or SFP ports + 2 SFP / 2.5G rear ports (fanless)
- 24 x 10/100Mbps PoE+ ports + 2 Combo 10/100/1000 or SFP ports + 2 SFP / 2.5G rear ports (PoE budget 370W)
- Layer 3: Local and Static Routing, DHCP relay, Proxy ARP, UDP fwdg,
- Security: 802.1X, IP Src Guard, DHCP Snooping, ARP Inspect.
- Convergence: Advanced QoS, Avaya Auto-QoS, 802.3af & 802.3at PoE+, ADAC, 802.1AB LLDP, MED, Location TLV.
- Resilient stacking*
- MLT/LACP (6grps x4 links), VLACP
- 16000 FDB entries
- 256 VLANs (port based)
- Nortel STP – 1 group
- 802.1s MSTP – 8 groups
- 802.1X – 32 EAP clients per port
Looks like stacking speed is limited to 10Gbps per switch. Not bad for what they are designed to do in a small wiring closet, but not usable in the data center.
