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

Truly, the best we could do
Format: Kindle
An excerpt from my analysis essay I submitted for my literature course: By revisiting her family’s past from before, during, and after the Vietnam War, she gained a deeper understanding of the emotional burdens her parents carried and the sacrifices they made that defined the entirety of their lives. Bui’s illustrated graphic memoir reveals that trauma does not simply disappear over time; instead, it becomes inherited, processed, and transformed. Through this process, Thi Bui is able to move toward empathy for her parents, acceptance of who they are, and a more complete sense of self.

Phenomenal. A must-read!
Format: Paperback
I first learned about this book only a week ago when visiting my sister for Thanksgiving in Eugene, Oregon. We went to the Jordan Schnitzer Museum of Art where I saw some work on display by the author, and there was a copy of her book available to look at, so I perused through and decided to buy it and read it. I'm so glad that I did! This is an incredible, poetic story that spans four generations, multiple wars and conflicts, and examines the fragility of the author's relationship with her parents and with her sense of place and motherhood. This book is one of the best I've read in a long time, and the art is moving and beautiful. It gave me new insight into the struggles of refugee life, and created a truly relatable narrative. I devoured this story in one Saturday. I highly recommend it.

Full review on nguyentoread.com
The Best We Could Do is Thi Bui's graphic memoir. Thi was born in Vietnam three months before the Vietnam War reached what we consider to be the end of the war. She came to America with her family in 1978. Bui's memoir spans multiple generations. In learning of her mother's and father's pasts, we learn the history of their parents. We see the struggles and pains of two people from very different walks of life trying to live during a time of war and chaos. We see glimpses of the agony everyone in the middle of the Vietnam War faced. Those who were not directly involved on either side but were caught in the middle of larger powers at war. This memoir more closely details the lives of her parents leading up to them arriving in America and making their life there. I was unsure if this memoir would focus largely on the experience of being a Vietnamese immigrant in America. There were parts that showed how it was for Bui's parents in a country where tensions were still high after the Vietnam War, where discrimination largely due to that was overt, and where degrees were not recognized and people who had spent their lives working and creating careers for themselves were not qualified for most work and had to hurdle multiple challenges to learn a language and complete education all over again if they wanted to provide a better life for their children. What Bui so beautifully captures in this memoir is the why behind how her parents were in raising her. Although Bui was born in Vietnam she was young when her family arrived in America. So I think her experience is one that many first generation Vietnamese-American people of my generation can understand and sympathize with. The wanting to know why their parents are the way they are but unable to ask because many have parents, like Bui's mother, who reluctantly share their stories and don't allow their children that glimpse that could help them better understand. In the panel which was most poignant to me, Bui draws her father as he looks over her work that would become The Best We Could Do. He says "You know how it was for me. And why later I wouldn't be... normal."
