Limitations and Restrictions

CMS Limitations and Restrictions

These limitations apply to CMS configuration:

• Host names and Domain Name System (DNS) server names that contain commas on a cluster

command switch, member switch, or candidate switch can cause CMS to behave unexpectedly. You

can avoid this instability in the interface by not using commas in host names or DNS names. Do not

enter commas when entering multiple DNS names in the IP Configuration tab of the IP Management

window in CMS.

• Access control entries (ACEs) that contain the host keyword precede all other ACEs in standard

access control lists (ACLs). You can reposition the ACEs in a standard ACL with one restriction: No

ACE with the any keyword or a wildcard mask can precede an ACE with the host keyword.

• CMS performance degrades if the Topology View is open for several hours on a Solaris machine.

The cause might be a memory leak. The workaround is to close the browser, reopen it, and launch

CMS again. (CSCds29230)

• If you are printing a Topology View or Front Panel View that contains many devices and are running

Solaris 2.6 with JDK1.2.2, you might get an Out of Memory error message. The workaround is to

close the browser, re-open it, and launch CMS again. Before you perform any other task, bring up

the view that you want to print, and click Print in the CMS menu. (CSCds80920)

• If a PC running CMS has low memory and CMS is running continuously for 2 to 3 days, the PC runs

out of memory. The workaround is to relaunch CMS. (CSCdv88724)

• When a VLAN or a range of VLANs is already configured and you specify a VLAN filter for a SPAN

session, the current configuration for that session is overwritten with the new entry. Although the

CLI appends new entries after the existing ones, CMS recreates the whole session, overwrites the

current entry, and provides only a single VLAN filter per entry. The workaround is to use the CLI.

It is the only method for specifying multiple VLANs for filtering in a SPAN session. (CSCdw93904)

• When you add a new member with a username and password that is different from the existing

cluster members username and password, CMS produces an exception error because of an

authentication failure. The workaround is to add the new member without any username and

password. When the new member is added to the cluster, remove the existing username and

password from the Username and Password fields, enter a new username and password, and then

apply it to all cluster members. (CSCdz07957)

• When the Link Graphs application has run for hours displaying packet drop and error information,

sometimes the X-axis crosses the Y-axis at a negative y value instead of at y = 0. This condition

occurs with all supported operating systems, browsers, and Java plug-ins. There is no workaround.

(CSCdz32584)

• CMS temporarily halts while starting. This occurs only when using Windows 98 and these

combinations of Netscape browser and Java run-time environment:

–

Netscape 4.75 and JRE 1.3.1 or 1.4.0

–

Netscape 6.2 and JRE 1.3.1

The workaround is to click once outside of the CMS Window. CMS then proceeds. (CSCdz72175)

• The SNMP dialog box changes size after clicking Apply or Refresh. This behavior has no affect on

SNMP functionality. There is no workaround. (CSCdz84255)

• When you enable log scaling for link graphs, the Y-axis scale becomes illegible. There is no

workaround. (CSCdz81086)
