5.
Verify that the two ends of an IRF link are operating at the same rate.
If you are using transceiver modules and fibers, verify that the transceiver modules at the two
ends of an IRF link are the same type. If the transceiver modules are not the same type, replace
them to be the same type.
6.
Verify that all IRF links are up:
a.
Execute the
display irf topology
command, and then check the
Link
field.
−
If the
Link
field for each IRF port does not display
DOWN
, go to step
−
If the
Link
field for an IRF port displays
DOWN
, go to step
b.
Execute the
display irf link
command, and then check the
Status
field of the physical
interfaces bound to the IRF port.
−
If the field displays
DOWN
or
ADM
(administratively down) for all the physical interfaces,
remove the link failures or use the
undo shutdown
command to bring up the
administratively down physical interfaces.
−
If the field displays
UP
for at least one of the physical interfaces, go to step
c.
Save the configuration, and then execute the
irf-port-configuration active
command in
system view to activate the IRF port configuration.
IMPORTANT:
Activating IRF port configuration requires a reboot. To prevent configuration loss, you must
save the configuration before you execute the
irf-port-configuration active
command.
7.
Verify that all member devices use the same software version:
a.
Execute the
display version
command to identify the software version of each member
device.
b.
Upgrade the software of all member devices to the same version.
NOTE:
Typically, the
irf auto-update enable
command can automatically synchronize a member
device with the software version of the master device. However, the synchronization might fail
when the gap between the software versions is too large. For more information, see the release
notes.
8.
Execute
display
commands to verify that all member devices use the same settings for the
following features:
System operating mode (set by using the
system-working-mode
command).
Hardware resource mode for the MAC address table, ARP and ND tables, and routing
tables (set by using the
hardware-resource switch-mode
command).
Enhanced ECMP mode (set by using the
ecmp mode enhanced
command).
Support for the IPv6 routes with prefixes longer than 64 bits (set by using the
hardware-resource
routing-mode ipv6-128
command).
Enabling status of packet loss prevention for OpenFlow forwarding (set by using the
openflow lossless enable
command).
VXLAN hardware resource allocation mode (set by using the
hardware-resource vxlan
command).
9.
If the issue persists, contact H3C Support.
