Trunk Operation Using The "Fec" Option On The 5300Xl Switches - HP ProCurve 6400cl Series Management And Configuration Manual

Use the Trunk option to establish a trunk group between a 5300xl, 3400cl, or
6400cl switch and another device, where the other device's trunking operation
fails to operate properly with LACP or FEC trunking configured on the 5300xl
or LACP trunking configured on the 3400cl or 6400cl. (FEC trunking is not
available on the Series 3400cl and Series 6400cl switches.)
Trunk Operation Using the "FEC" Option
on the 5300xl Switches
This section applies only to the Series 5300xl switches.
This is the most flexible method for distributing traffic over trunked links on
a 5300xl switch when connecting to devices that use the FEC (Fast EtherChan­
®
nel ) technology. FEC trunks offer the following benefits:
■ Provide trunked connectivity to a FEC-compliant server, switch, or router.
Enable quick convergence to remaining links when a failure is detected
■
on a trunked port link.
Depending on the capabilities of the device on the other end of the trunk,
■
negotiate the forwarding mechanism on the trunk to the non-protocol
option.
■ When auto-negotiated to the SA/DA forwarding mechanism, provide
higher performance on the trunk for broadcast, multicast, and flooded
traffic through distribution in the same manner as non-protocol trunking.
Support FEC automatic trunk configuration mode on other devices. That
■
is, when connecting FEC trunks to FEC-capable servers, switches, or
routers having FEC automatic trunk configuration mode enabled, the FEC
trunks allow these other devices to automatically form trunk groups.
