Link Aggregation Configuration - 3Com 4210 PWR Configuration Manual

Link Aggregation
Configuration
Load-sharing aggregation resources are allocated to aggregation groups in the
following order:
An aggregation group containing special ports which require hardware
■
aggregation resources has higher priority than any aggregation group
containing no special port.
A manual or static aggregation group has higher priority than a dynamic
■
aggregation group (unless the latter contains special ports while the former
does not).
For aggregation groups, the one that might gain higher speed if resources
■
were allocated to it has higher priority than others. If the groups can gain the
same speed, the one with smallest master port number has higher priority than
other groups.
When an aggregation group of higher priority appears, the aggregation groups of
lower priorities release their hardware resources. For single-port aggregation
groups, they can transceive packets normally without occupying aggregation
resources
c
CAUTION: A load-sharing aggregation group contains at least two selected ports,
but a non-load-sharing aggregation group can only have one selected port at
most, while others are unselected ports.
c
CAUTION:
The commands of link aggregation cannot be configured with the commands
■
of port loopback detection feature at the same time.
The ports where the mac-address max-mac-count command is configured
■
cannot be added to an aggregation group. Contrarily, the mac-address
max-mac-count command cannot be configured on a port that has already
been added to an aggregation group.
MAC-authentication-enabled ports and 802.1x-enabled ports cannot be added
■
to an aggregation group.
Mirroring destination ports cannot be added to an aggregation group.
■
Ports configured with blackhole MAC addresses, static MAC addresses,
■
multicast MAC addresses, or the static ARP protocol cannot be added to an
aggregation group.
Ports where the IP-MAC address binding is configured cannot be added to an
■
aggregation group.
Port-security-enabled ports cannot be added to an aggregation group.
