SAN switch 2/32 Version 4.0.2b Release Notes
Version 4.0.2b. Fabric OS Version 4.0.2b and all subsequent versions include
the most current patch level of v15.3.1.4 of the SNMP Research agent, which
SNMP Research has indicated is not susceptible to the vulnerability described
in notes VU#854306 and VU#107186.
■
SNMP trap recipients have been linked to the Access Control List (ACL).
In order for an SNMP Management Station to receive a trap generated by the
agent, the administrator must configure a trap recipient to correspond to the IP
address of the Management Station using the
agtcfgset
command. In
addition, the trap recipient must be able to pass the ACL check.
The ACL check is as follows:
There are six ACLs to restrict SNMP get/set/trap operations to hosts under a
host-subnet-area. Host-subnet-area is defined by comparing non-zero IP
octets. For example, an ACL of
192.168.64.0
allows for access by any hosts
that start with the specified octets. The connecting host is enabled to set each
host-subnet-area to be read-write or read-only. Highest privilege matched out
of six entries is given to the access.
The ACL check is turned off when all six entries contain
0.0.0.0
.
Fabric OS Commands
The following Fabric OS commands are included with this release of firmware.
ifModeShow
and
ifModeSet
Commands
Changing the link mode is not supported for all network interfaces or for all
Ethernet network interfaces. These commands are only functional for the “eth0”
interface. For dual-CP systems, the
ifModeSet
command affects the CP that
you are currently logged into. To set the link operating mode on the active CP you
must issue this command on the active CP. To set the link operating mode on the
standby CP you must issue this command on the standby CP. During failover the
link operating mode is retained separately for each CP, since the physical links
may be set to operate in different modes.
Note:
Exercise care when using these commands. Forcing the link to an operating
mode not supported by the network equipment to which it is attached may result in an
inability to communicate with the system through its Ethernet interface.
