Example 81 Example showing information about the forwarding port
HP Switch# show trunks load-balance interface trk1 mac 424521-498421 534516-
795463 inbound-port a5
Traffic in this flow will be forwarded out port 23 based on the confiugred L2
load balancing.
Operating notes
The port cannot be determined if:
• All the ports in the trunk are down.
• The MAC address is all zeros.
• The source MAC address is broadcast or multicast.
Distributed trunking
Configuring ISC ports
You must configure the ISC ports before you can configure the trunks for distributed trunking.
Syntax
switch-interconnect [ port-num | trk1...trkN ]
no switch-interconnect
Configures an InterSwitch-Connection (ISC) port. The
[ port-num | trk1...trkN ]
variable is the interconnect interface that connects two distributed trunking switches. It can be a
physical port, manual LACP trunk, or manual non-protocol trunk. You can override an ISC
configuration by configuring the command with a different value.
The no form of the command removes the ISC interface configuration.
NOTE: A port that is already part of a trunk cannot be configured as an ISC interface.
Configuring distributed trunking ports
Distributed trunking ports must be configured manually.
Syntax
trunk <port-list> trk1 | trk2 ... trkN [ trunk | lacp | dt-lacp |
dt-trunk ]
no trunk <port-list>
Configures distributed trunking on a switch. Use either the dt-lacp ordt-trunk option.
The trunk groups and trunk types must be identical in both switches. For example, if Switch Local
is configured with trk1and uses the dt-lacp option, Switch Remote also must be configured
with trk1 and use the dt-lacp option to form a distributed trunk. Similarly, if Switch Local is
configured with trk2 and uses the dt-trunk option, Switch Remote must be configured with
trk2 and use the dt-trunk option to form the distributed trunk.
The no form of the command removes the distributed trunking configuration on the switch.
Example
Figure 54 (page 141) shows an ISC port being configured for the local switch and the remote switch.
