other text editor that will not add formatting codes to the file. When saving the file, do not
change the ".cfg" extension in the filename or save the file with formatting codes.
Enhanced stacking. The IP address 172.16.16.16 is reserved for the enhanced stacking
feature. Do not assign this address to any device in the same subnet as an enhanced stack.
Login password. The maximum length of a login password is 16 alphanumeric characters for
manager accounts created through the RADIUS and TACACS+ authentication protocols and
supplicant accounts for 802.1x port-based network access control. Passwords that exceed
this limit will not work.
TACACS+. The TACACS+ client software on the switch supports Password Protection
Protocol (PAP), but not Challenge Handshake Authentication Protocol (CHAP) or AppleTalk
Remote Access Protocol (ARAP). (1078)
Port settings. When removed from a port trunk, a port retains the settings (e.g., speed and
duplex mode) that it had as a member of the trunk. The parameter settings are not returned
to the default values. (2144)
MAC addresses. You must move the cursor manually from field to field when entering an IP
or MAC address in the web browser interface. The cursor does not move automatically as
you enter the parts of an address. (1699, 2123)
SNTP. The SNTP client software on the switch sends a Transmit Time Stamp with a value
NULL when synchronizing with a Network Time Protocol server. This does not affect the
operation of the SNTP client software. (1676)
IGMP snooping. When IGMP snooping is enabled and ingress filtering is disabled, the switch
does not register tagged IGMP queries in the IGMP routers list. (1493)
SFP modules and the AT-9408LC/SP switch. Always disconnect the fiber optic cable from an
SFP module in an AT-9408LC/SP switch before removing the module. The L/A LED for the
slot may remain on if you remove an SFP module while it has a link to an end node. This
problem does not affect the operation of the switch or the SFP slot. The L/A LED goes off the
next time you install an SFP module in the slot.
"set stack" command. When you are in a standalone (and Auto mode) configuration, the
command "set stack moduleid=1 newmoduleid=static" does not work. You must enter "set
stack moduleid=1 newmoduleid=1" for the standalone configuration. When you are in a
stacking configuration, either of the above commands will work.
