This combination of highly integrated N-Chips connected through the F-Chip gives the ProCurve 5300xl Switch Series the ability to deliver wire-speed Layer 3 for the price of Layer 2 switching, and in a chassis form factor.
As mentioned in the previous section, one of the functions of the N-Chip is to analyze each packet’s header as it comes into the switch. The packet’s addresses can be read, with the switch making forwarding decisions based on this analysis. For example, if a packet’s 802.1Q tag needs to be changed to re-map the packet priority, the N-Chip needs to look at each packet to see if any particular one needs to be changed.
F-Chip The fabric, or F-Chip, which is located on the backplane of the switch, provides the crossbar fabric for interconnecting the modules together. The use of a crossbar allows wire speed connections simultaneously from any module to any other module. As mentioned in the N-Chip section, the connection between the F-Chip and each N-Chip (module) in the chassis is through a 9.6Gbps full duplex link.
For example, the Switch xl 100/1000-T module, which has 4 100/1000 ports, has whereas the Switch xl 10/100Base-TX module, which has 24 10/100 ports has 4096÷24 = 170 outbound packet buffers per port.
5.76 μsec for a 64 byte packet, and 122.08 μsec for a 1518 byte packet itself to move into and out of the switch. At 1Gbps a 64 byte packet takes 576 ηseconds, while a 1518 byte packet takes 12.208 μsec. Adding the packet receive time to the latency is proper because this extra time is seen externally to the switch by the network and figures in to the transit time of the packet as it moves through the network.
Port security, MAC lockdown and MAC lockout protection – Restrict access to the network through the switch port based on the connected host MAC address. • Static NAT – hide up to 32 nodes per switch from the rest of the network through static IP address translation.
Alert Log capability which finds common network problems and informs the net manager of the situation • SNMP v1, v2 and v3, SNMP Traps and MIB II support to manage the switch from a network management station. • Ability to configure a network monitoring port (mirror port) for use with external probes or analyzers •...
High Availability IP Routing IP routing on the ProCurve 5300xl Switch Series is done in the ASIC at wire speed by the user defining VLANs and then specifying routing between them. Some of the IP services available are: •...
Series can perform Layer 3 routing, there is an easier solution in Switch Meshing, which is described in the next section. The second concern is on link failure or loss of the STP root switch, Spanning Tree can take up to 45 seconds to re-establish network connections. In many networks a potential outage of 45 seconds is unacceptable.
Configuration of Switch Meshing is trivial. Specifying which ports are part of the Switch Meshing domain is all that is needed. The switch takes care of the rest. This is in sharp contrast to configuration of routing protocols, which can be challenging.
Other ProCurve switches that support Switch Meshing, such as the ProCurve Switch 4000M family, will work together in a mesh with the ProCurve 5300xl Switch Series. There are a few corner case caveats in this type of mixed environment that are covered in the ProCurve 5300xl documentation.
“IEEE 802.1p Priority Support”. The 802.1p bits are also set for the outbound packet if the packet goes out of the switch through a port that has 802.1Q tagging turned on. For diffserv, each of the diffserv code points (DSCP) can have a priority set for it. It is also possible to set a new DSCP and 802.1p priority based on the incoming DSCP, or set the...
IEEE 802.1Q packet tagging supports both designation of VLAN membership (see the VLAN section below) and packet priority (up to 8 levels and often referred to as 802.1p). Since 802.1p has 8 levels of priority possible, but the switch has only 4 physical priority levels, the following mappings are used: 802.1p priority...
If a host appears to exhibit the worm-like behavior of attempting to establish a large number of outbound IP connections (destination addresses, or DAs) in a short period of time, the switch responds depending on how connection-rate filtering is configured.
SA for a “penalty” period and generates an Event Log notice of this action and (if a trap receiver is configured on the switch) a similar SNMP trap notice. When the penalty period expires the switch re-evaluates the routed traffic from the host and continues to block this traffic if the apparent attack continues.
Static filtering can be used to provide security and/or bandwidth control within the network. When a static filter is defined it can be applied to any or all ports on the switch. The following three types of static filters can be defined: •...
One point to note about 802.1X access control is that it is control to the port of the switch. Once access is given to the switch port, anyone connected through this port will have access to the services associated with the user that authenticated.
These parameters are sent as RADIUS attributes and the switch then applies them to the client access port for the duration of the connection. With ProCurve IDM solution, ProCurve 5300xl Switch Series can dynamically apply VLAN, QoS and bandwidth rate-limit policies to the users based on location, time and system.
SSH session that is initiated. The host key pair is used to authenticate the SSH client and switch to each other. The host key pair is stored in flash, so is not lost on reboot, power-cycle or by clearing the config file.
(unless the switch is reset to its factory-default configuration). Instead, if the log is filled when the switch detects a new intrusion, the oldest entry is dropped off the listing and the newest entry appears at the top of the listing.
Gigabit (8 Gigabit full-duplex) link. Fiber-optic links can be trunked to interconnect switches across large campuses. Port trunking also provides redundancy on links between the two switches or switch and server. If one of the links fails, the traffic is moved to another link in the trunk in under one second.
VLAN on switches throughout a Layer 2 domain when that VLAN has been statically configured on at least one switch in the domain. The intention with GVRP is to automatically interconnect a VLAN that is manually configured on two switches that are not contiguous in a Layer 2 domain.
Guaranteed Minimum Bandwidth operates at the port or switch level, with values specified as desired for each priority queue.
ProCurve 5300xl Switch Series are: • Web-based management - Configuration of the individual switch can be done anytime, anywhere through the web server available in each switch, accessible via a standard web browser. • ProCurve Manager (PCM) – A Windows-based network management solution that is included in-box with ProCurve 5300xl Switch Series.
• HP OpenView platforms - If management of a generic (ProCurve and other vendors’ devices) or large (>1500 managed nodes) IP network is needed: NT platform – ProCurve Network Management for OV-NT (J4869B) can be separately purchased to provide direct management of the ProCurve 5300xl Switch Series and other ProCurve products through HP OpenView/NT.
• Setup – provides a quick, simple one screen menu to set up the switch for items such as IP address, time protocol method, community name, spanning tree, etc. without having to use the command line interface. Particularly useful for getting an IP address into the switch so that additional configuration can be done through the browser GUI.
The ProCurve 5300xl Switch Series have a limited lifetime warranty, for as long as you own the product. If any part of the switch fails due to a defect in material or workmanship, including the power supply or fans, it will be replaced.
In addition to free support services such as the warranty and telephone support, ProCurve offers an extensive range of fee-based support services to meet more specialized needs. The following optional services are available for the ProCurve 5300xl Switch Series: •...
5300 series switches in a meshed – at layer 2 or layer 3 – highly available configuration or grid. Over time more features will be added to the ProCurve Switch 5300 Series to round out the intelligent control to the edge, filling in the command from the center, providing a dynamic network environment needed by users in a rapidly evolving information environment.
The intelligence and throughput of the ProCurve Series 5300xl switch make it suitable for applications at or near the edge of networks of all sizes, or in the center of networks that are small-to-moderate in size; the switch’s modular structure gives you the flexibility to tailor the switch to match your topology’s requirements.
The ProCurve 5308xl Switch is the same as the ProCurve 5304xl Switch, except that it holds up to 8 modules in a 5U rack space, giving it a higher port density and greater throughput than the ProCurve 5304xl Switch.
