Wireless Edge Services zl Module Release Notes WT.01.15

■ L2-L3 (40107) — DHCP boot file names are limited to 63 characters in both the CLI and
the web management interface.
■ L2-L3 (40163) — The DHCP hostname field is unable to accept non-alphanumeric
characters.
■ Redundancy (41949) — A wireless station may show up on multiple modules in a
redundancy group after failing over from a module that was removed from the switch.
Connectivity and traffic for the wireless station are not affected.
Workaround: The genuine current wireless station owner is the one with the shortest amount of
time in the "Last Active" field in the Device Information -> Wireless Stations -> Details button.
■ Security (36833) — The integrated firewall feature is supported only for packets received
on Layer 3 interfaces. For packets getting switched, no firewall protection is applied. The
firewall functionality supports protection against various network level attacks and inspects
each packet for possible corruption that can indicate some kind of attack.
■ Security (41086) — The ACL logging functionality is not available for Layer 2 or WLAN
ACLs.
■ Security (39537) — FTP control packets are not getting appropriately marked when a
standard access list is configured for marking TOS bits.
■ Security (1000460306) — MAC filter rules are designed to apply to the association
process. If a wireless station is already associated, a new “deny” MAC filter configured
through Security -> MAC Filter in the web management interface does not take effect until
the station re-associates. If the administrator wants the filter to take effect immediately, the
wireless station should be disconnected via Device Information -> Wireless Stations ->
Disconnect. Rules configured in the latter context take effect immediately.
■ Security (1000460347) — Adding a MAC Filter via the web management interface (Device
Information -> Wireless Stations -> Disconnect screen) only associates the rule to WLANs
1-64.
■ SNMP (39709) — Configuration options that have been initiated but not saved in the CLI
context cannot be edited via the web management interface. An "SNMP Exception" message
will occur with the failure.
Workaround: Save any changes made in the CLI from the CLI prior to attempting to edit them
through the web management interface.
■ SNMP (40513) — An SNMP timeout occurs when a DHCP option value containing more
than 100 characters is entered in the DHCP pool configuration.
Workaround: Keep the configuration of option values to 100 characters or less.
■ SNMP (39823) — An SNMP timeout error may occur while generating a 2048 byte RSA key
for use with a certificate.
Workaround: Confirm that the key was not generated; sometimes the key gets generated but a
false error message is produced. If the key was not generated, retrying key generation should
resolve the issue.
