Port Trunking Trunk Group Operation Using LACP Static LACP Provides a manually configured, st atic LACP trunk to acco mmodate these conditions: LACP Port T runk Configuration Operation • The port on the other end of the trunk link is configured for a static LACP trunk.
Port Trunking Trunk Group Operation Using LACP Default Port Operation In the default configuration, LACP is di sabled for al l ports. If LACP i s not configured as Active on at least one end of a link, then the p ort does not t ry to detect a trunk configur ation and operates as a standard, untrunked port.
Port Trunking Trunk Group Operation Using LACP LACP Partner Ye s : LACP is enabled on both ends of the link. Status Name Meaning No: LACP is enabled on the switch , but either LACP is not enabled or the link has not been detected on the opposite device.
Port Trunking Trunk Group Operation Using LACP The switch will not allo w you to configure LACP on a port on which port security is enabled. For example: ProCurve(config)# int a17 lacp passive Error configuring port A17: LACP and port security cannot be run together.

Port Trunking Distributed Trunking Distributed T runking Overview The IEEE standard 802.3ad requires that all the links in a trunk group originate from the same switch. Di stributed T runking uses a proprietary p rotocol that allows two or more por t trunk links dist ributed across two switch es to create a trunk group.
12-28 Port Trunking Distributed Trunking Figure 12-13. Example of Distribu ted T runking Confi guration In figure 12-14, three differ ent distributed trunk s with three different servers have one common ISC link. Each trunk only span s two distributed trunki ng switches.

Switches that have config- urations with bps values w ill be auto matically converted when you update your software to the new version.
Port Traffic Controls Rate-Limiting • Kbps rate-limiting is done in segments of 1% of the lowest corresponding media speed. For example, if the media speed is 100 Kbps, the valu e would be 1 Mbps.

Port Traffic Controls Rate-Limiting rate-limiting o n the port while it is in the trunk. Atte mpting to configure rate-limiting on a po rt that alread y belongs to a trunk generates the following message: < port-list > : Operation is not allowed for a trunked port.
Port Traffic Controls Rate-Limiting ■ Optimum rate-limiti ng operation: Optimum rate-li miting occurs with 64-byte packet sizes. T raffic with larger packet sizes can result in performance somewhat below the configured band width. This i s to ensure the strictest possible rate-l im iting of all si zes of packets.
Port Traffic Controls Rate-Limiting messages to an extent where no other tr affic can get through. (ICMP messages themselves can also be misused as viru s carriers).
Port Traffic Controls Rate-Limiting Spoofe d Ping: An ICMP echo request packet intentionally gen erated with a valid source IP address and an inva lid destin ation IP address. Spoofed pings are often created with the intent to oversubscribe network resources with traffic having invalid destinations.
Port Traffic Controls Rate-Limiting Configuring ICMP Rate-Limiting The r ate-limit icmp command controls inbound usage of a port by setting a limit on the bandw idth available for inbound ICMP traffi c.
Port Traffic Controls Rate-Limiting Using Both ICMP Rate-Limiting and All-T raffic Rate-Limiting on the Same Interface ICMP and all-tra ffic rate-limiting can be confi gured on the same interface.
Port Traffic Controls Rate-Limiting For example, if you wanted to view the rate-lim iting configuration on th e first six ports in th e module in slot “B”: ProCurve(config)# show rate-li mit icmp .
Port Traffic Controls Rate-Limiting 0.5 Mbps of inbound traffi c. If an interface experiences an inbound flow of ICMP traffic in excess of its config u red limit, the swit ch gene rates a log message and an SNMP tr ap (if an SNMP trap receiver is conf igured).
Note on T esting ICMP Rate-Limiting Port Traffic Controls Rate-Limiting ICMP rate-limiti ng is applied to the a vailable bandwidth on an interface. If the total bandwi dth requested by all ICMP traffic is less than the ava ilable, configured maximum rate, then no ICMP ra te-li mit can be applied.
Port Traffic Controls Rate-Limiting The switch does not send more traps or Event Log messages for excess ICMP traffic on the affect ed port until the system operat or resets the port’ s ICMP trap function . The reset can be done throug h SNMP from a network manage - ment station or t hrough the CLI with the following setmib co mmand.
Port Traffic Controls Rate-Limiting T o match the port’ s external slot/numbe r to the internal port number , use the walkmib ifDescr command, as shown in the following figure: ProCurve# walkmib ifDescr ifDescr.1 = A1 ifDescr.2 = A2 ifDescr.3 = A3 .
Port Traffic Controls Rate-Limiting Syntax: rate-limit < bcast | mc ast > in percent <0-100> no rate-limit <bcast | mcast> in Enables rate-limiting and set s limits for the specified inbound broadcast or multicast traffic. Only the amount of traffic specified by the percent is forwarded.

Port Traffic Controls Jumbo Frames ■ When the switch applies the default MT U (1522-bytes) to a VLAN, all ports in the VLAN can receive in coming frames of up to 1522 bytes in length. When the switch applies the jumbo MT U (9220 bytes) to a VLAN, all ports in that VL AN can recei ve incomi ng frames of u p to 9220 bytes in len gth.
Port Traffic Controls Jumbo Frames can occur in situations where a non -jumbo VLAN in cludes some ports that do not belong to another , jumb o-enabled VL AN and some port s that do belong to another , jumbo-enabled VL AN.
Port Traffic Controls Jumbo Frames T roubleshooting A VLAN is configured to allow jum bo frames, but one or more ports drops all inbound j umbo frames. The port may not be operating at a min- imum of 10 Mbps on the ProCurve 3500 switches or 1 Gbps on the ot her switches covered in this guide.
