Summit Family Switches
PD4-1545964372 On a Summit X480 switch, the log message Setting hwclock time to system
time, and broadcasting time is frequently displayed.
PD4-2094910917 An LDAP bind fails after a system reboot.
PD4-2026467027 When a Summit X670V-48x switch with a 40G port in partition mode connected to a 10G
port using MTP breakout cables, the 10G side shows the link is up.
PD4-1950680298 On a Summit X670V-48x switch, inserting a copper GBIC (1000BASE-T) in a 10G
capable port changes the speed and duplex setting of the port.
PD4-1996237147 On a Summit X670 switch, the power fan controller is not disabled when using the
disable command with the all option.
PD4-2093228351 On a Summit X670 series switch, FDB identities are not flushed from the identity
management table.
PD4-2095792132 When clearing an FDB entry or updating a policy entry on VM-tracking, MAC addresses
with a wide key policy installed results in the policy being uninstalled. When this occurs,
the following error message is displayed:
ACL filter install failed on vlan *, port 1:16, rule
"VM1:16_00:00:11:00:00:1a_E601" index 601, Invalid parameter
(user-defined field (UDF))"
PD4-1824530443 The following behavior differences were observed between a Summit X480 and a
Summit X450a switch:
• Configured a general query interval of 125 seconds but a Summit X480 switch sends
general queries every 130 seconds. This issue is not seen on a Summit X450a
switch.
• A Summit X480 is sending both MLDv1 and MLDv2 reports even though only MLDv2
is enabled. This issue is not seen on a Summit X450a switch.
PD4-1436226210 With default ethertype (0x88a8) configured, Summit X460 and X480 switches do not
display an error message when adding a port as tagged to a VMAN when the port is
already part of a tagged VLAN. When the port is already part of an EAPS control VLAN,
EAPS goes to a failed state.
PD4-1721719301 The process HAL crashes with signal 11 after configuring a primary and secondary
pseudo wire and sending unicast traffic through the pseudo wire.
