Netra Proxy Cache Server Product Notes

Known Problems

We are aware of the following problems with the Netra Proxy Cache product at the time of publication:

If you have a serial (TTY) connection to an unconfigured Netra Proxy Cache Server and monitor console output upon initial boot you see a message such as:
```
<date><time> NewNetra snmpXdmid: Registration with DMI failed. err = 831.
```

You might also see a message such as:

<date><time> NewNetra snmpdx: SNMP error (genErr(5), 1) sent back to localhost.
<portnum>

Following configuration of your machine, you should not see these messages. The messages can safely be ignored as they do not reflect a problem with the server or the SNMP agent.

If you do see a message from snmpd or snmpdx following configuration, enter the following command to restart the SNMP master agent (snmpdx):

# /opt/SUNWoam/bin/snmpreset

If the name of the last host in the table of parent and sibling proxy caches cannot be resolved at the time a Netra Proxy Cache Array host starts, that host will be unable to use other hosts in the array as siblings. Messages such as the following are generated every minute in the cache log file:
```
[
<date><time>] neighbors.c:1617:   membership_update: discovered new neighbor: SCALR:0x80827257
[<date><time>] neighbors.c:1661:   add_neighbor_scalr_ip_list: too many neighbors
```

Workaround: Rearrange the table of parents and siblings so that the host with the unresolvable name is not last. As with any configuration modification, you must use the Install Configuration link the Proxy Cache Administration page after you make the change.

In the Proxy Cache Monitoring for Host page (described on page 13-2 of the Netra Proxy Cache Server User's Manual), the values displayed for SSL Connections, both total and current, are not reliable. The SSL Connections row is in the Proxy Cache Connection Statistics table in the Proxy Cache Monitoring for Host page.

The problem referred to in the preceding paragraph manifests itself in the SNMP variables currentSSLConnections and totalSSLConnections, in the group proxyClientStatGroup. If you use an SNMP-conformant management platform, such as Solstice Domain Manager, to retrieve these variables, you might obtain an inaccurate value.
