Description
HP ProCurve 2810-48G, 48-port Gigabit Switch P/N: J9022A, J6022-60001NEW Open BoxQuality of Service (QoS) Class of Service (CoS) sets the IEEE 802. 1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP UDP port number, source port, and DiffServ Layer 4 prioritization enables prioritization based on TCP UDP port numbers Traffic prioritization (IEEE 802. 1p) allows real time traffic classification with support for eight priority levels mapped to four queues Connectivity Dual personality functionality
Quality of Service (QoS)
- Class of Service (CoS) — sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ
- Layer 4 prioritization — enables prioritization based on TCP/UDP port numbers
- Traffic prioritization (IEEE 802.1p) — allows real-time traffic classification with support for eight priority levels mapped to four queues
Connectivity
- Dual-personality functionality — four 10/100/1000 ports or SFP slots for optional fiber connectivity such as Gigabit-SX, -LX, and -LH, or 100-FX
Resiliency and high availability
- IEEE 802.3ad Link Aggregation Protocol (LACP) and HP port trunking — support up to 24 trunks, each with up to 8 links (ports) per trunk
- IEEE 802.1s Multiple Spanning Tree — provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for IEEE 802.1d and IEEE 802.1w
- Optional redundant power supply — provides uninterrupted power (provided by HP 600 RPS/EPS)
Manageability
- sFlow (RFC 3176) — wire-speed traffic accounting and monitoring
- RMON (remote monitoring) — provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events
- Dual flash images — provides independent primary and secondary operating system files for backup while upgrading
- Troubleshooting — ingress/egress port monitoring enables network problem-solving
- Single IP Address Management — single IP address management for a virtual stack of up to 16 switches
- Multiple configuration files — allow multiple configuration files to be stored to a flash image
Layer 2 switching
- VLAN support and tagging — supports IEEE 802.1Q (4,094 VLAN IDs) and 256 VLANs simultaneously
- GARP VLAN Registration Protocol — allows automatic learning and dynamic assignment of VLANs
- Jumbo packet support — supports up to 9220-byte frame size to improve the performance of large data transfers
Security
- Port security — allows access only to specified MAC addresses, which can be learned or specified by the administrator
- Protected ports — provides increased security by allowing specified ports to be isolated from all other ports on the switch; the protected port or ports can communicate only with the uplink or shared resources
- MAC address lockout — prevents particular configured MAC addresses from connecting to the network
- Multiple user authentication methods —
- IEEE 802.1X — is an industry-standard method of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server
- Web-based authentication — similar to IEEE 802.1X, it provides a browser-based environment to authenticate clients that do not support the IEEE 802.1X supplicant
- MAC-based authentication — client is authenticated with the RADIUS server based on the client's MAC address
- Switch management logon security — can require either RADIUS or TACACS+ authentication for secure switch CLI logon
- Multiple IEEE 802.1X users per port — provides authentication of up to two IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication
- STP BPDU port protection — blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
- Secure FTP — allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of a switch configuration file
- RADIUS/TACACS+ — eases switch management security administration by using a password authentication server
- Source-port filtering — allows only specified ports to communicate with each other
- Secure Shell — encrypts all transmitted data for secure remote CLI access over IP networks
- Secure Sockets Layer (SSL) — encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
Convergence
- IP multicast snooping and data-driven IGMP — automatically prevent flooding of IP multicast traffic
- IEEE 802.1AB Link Layer Discovery Protocol (LLDP) — is an automated device discovery protocol that provides easy mapping of network management applications
- Per-port broadcast throttling — selectively configures broadcast control on heavy traffic port uplinks
- Software updates — free downloads from the Web
Ease of use
- Locator LED (switch) — allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches
- Friendly port names — allow assignment of descriptive names to ports
- Find-Fix-and-Inform — finds and fixes common network problems automatically, then informs administrator
- HP/IEEE Auto-MDIX — automatically adjusts for straight-through or crossover cables on all RJ-45 ports

Suprisingly good quality and a great looking jacket
I have been searching for a ring master jacket for a circus themed gala where I will be the Auctioneer/Ring Master. All the other jackets I looked at were either cheap costume stuff or just looked a little too much military Hussar style with all of the added gold tassels. This has just the right class and definitely the right look. I was worried it would fit weird or just not be constructed well but I could not be any happier with this jacket- the sleeves are a perfect length when my arms hang at my side, as is the high waist cut and the length of the tails are also just right- and best of all the sequins really shine.
I spent my career in the circus and the performing arts and this would have been more than acceptable on stage for someone to wear as a ring master or to look fancy and sparkly, assuming nobody will be standing on your shoulders and popping off your sequins. It is comfortable to wear, although I would not say it allows for full range of motion relative to a costume I would have actually worn in a circus while doing acrobatics. But that would be a totally hand made costume with flexible material and 4-10x the price.
Overall it cannot be beat for your average wearer!

Well Made, Runs A Little Small
I bought this on short notice for a drag show. I wasn't expecting a whole lot, but it exceeded my expectations in a lot of ways. The interior feels like the inside of a standard suit coat, and is comfortable for long term wear. The sequins are sewn on in a pattern, and there's little, if any, fallout. I've only found a couple sequins on the floor.
I've used it a lot since the drag show, for a lot of things (live streams, videos, etc). Absolutely worth the price, and I've already gotten my money's worth out of it.
It does run a little small, but it still mostly fits according to the size chart.
A few notes:
- It doesn't have button holes, so if you're looking for something that buttons up, look elsewhere.
- Washing instructions say to machine wash cool, warm iron (do not tumble dry, do not dry clean). I'd say run it on the gentlest cycle you can muster, or just spot clean stains and the pits (if you're sweaty). I don't know how well this thing would survive a wash, but I haven't needed to wash it yet.
