Features and benefits


Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers


Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues


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


Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue guaranteed minimums


Bandwidth shaping: Rate limiting: provides per-port, ingress-based enforced bandwidth maximums


Guaranteed minimums: provides per-port, per-queue egress-based guaranteed bandwidth minimums


Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network


Management


Remote configuration and management: is available through a secure Web browser or a command-line interface (CLI)


Manager and operator privilege levels: enable read-only (operator) and read-write (manager) access on CLI and Web browser management interfaces


Management VLAN: segments traffic to and from management interfaces, including CLI/telnet, a Web browser interface, and SNMP


RADIUS accounting support: separates RADIUS accounting server support per SSID; provides detailed session, usage, and billing information for each client activity


Multiple configuration files: can be stored to the flash image


Dual flash images: provide independent primary and secondary operating system files for backup while upgrading Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS


Command-line interface (CLI): provides a secure, easy-to-use command-line interface for configuring the module via SSH or a switch console; provides direct real-time session visibility


SNMPv1, v2c, and v3: facilitate centralized discovery, monitoring, and secure management of networking devices


Port mirroring: enables traffic on a port to be simultaneously sent to a network analyzer for monitoring


Connectivity


Optional 10 Gigabit Ethernet ports: allow the addition of 10 Gigabit Ethernet connections for uplinks or high-bandwidth server connections; flexibly supports XFP, SFP+, or CX4 local connections


Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports


Dual-personality functionality: includes four 10/100/1000 ports or SFP slots for optional fiber connectivity such as GigabitSX, -LX, -LH, or 100-FX


IEEE 802.3af Power over Ethernet (PoE): provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras

cute but not the material I expected
Size: Small, Color: Pure Black
This was really cute, well made and fit as expected. Unfortunately, I have sensitive skin and I found the material to be scratchy so I sent it back.

Nice quality sweater, well made and soft.
Size: Large, Color: Pure Beige
I love this sweater - but I bought it just in time for summer, so it won't get much use until fall! It fits great, it is really soft and the overall quality is quite good. I plan to buy another one in another color as well.

Nice casual looking sweater
Size: Small, Color: Pure Black
I purchased the black/cream inset sweater in a small. I usually wear a small. I fits loose, but NOT baggy. I like the loose fit. The sweater feels so soft. Nice looking sweater. Very happy with the sweater, but could have ordered a medium for a boxier fit.
