Chapter 6 The System Chassis’s Integrated Switch 6-3
■4871779: Blades areunable to receive multicast packets when IGMP querying is
enabled.
Multicasting on the switch does not work correctlyif the IP address for the switch
is not configured. This is only likely to be the case if the IP address is configured
by DHCP and the DHCP process has failed for any reason. If necessary,you can
work around the problem by specifying an IP address for the switch manually:
■4885056: The switch does not have ingress filtering enabled by default.
By default ingress filtering is set to disabled. This allows packets from VLANs
other than the VLANs explicitly enabled on each port to pass through the switch.
This is a security risk. Toenable ingress filtering on the switch, you must enable it
on each port individually.The following example demonstrates how to enable it
for NETP0. Repeat the commands for each port (fromNETP1 through NETP7 and
SNP0 through SNP15) and aggregate link (port-channel):
■4894936: Auto-negotiation and speed/duplex mode cannot be configured on the
NETMGT port
The NETMGT port’s speed and duplex mode are fixed at 100Mbps and full
duplex. This is not manually configurable. However,it is possible to connect to
the NETMGT port using a 10BaseT full- or half-duplex connection, or a 100BaseT
full- or half-duplex connection. If you do this, the switch’s internal hub negotiates
the speed and duplex mode automatically with the interface at the other end of
the connection. If you attempt to set the speed and duplex mode for NETMGT
manually,you will receive an error message to the effect that the interface
ethernet NETMGT speed-duplexcommand failed. In future releases of the
switchfirmware the error message will explain that NETMGT cannot be manually
configured using this command.
■4780304: Adding aport to the forbidden VLAN list sometimes fails to remove the
VLAN from that port’s VLAN list
This error is only seen when the port you aretrying to add to the forbidden list is
the last VLAN on that port’s VLAN list (apart from the native VLAN, which can
never be removed). Firmware that fixes this problemis now available from
http://sunsolve.sun.com (patch number: 114783-xx).
