Brocade 6505 configuration 2 All switches in the fabric maintain the current clock server IP address in non-volatile memory. By default, this value is LOCL, the local clock server of the Principal (when FCS not enabled) or Primary (when FCS is enabled) switch. Changes to the clock server value on the Principal or Primary switch are propagated to all switches in the fabric. When a new switch enters the fabric, the time server daemon of the Principal or Primary switch sends out the addresses of all existing clock servers and the time to the new switch. If a switch with Fabric OS v5.3.0 or later has entered the fabric, it will be able to store the list of all the clock server addresses; switches running Fabric OS versions earlier than v5.3.0 will ignore the new list parameter in the payload and will update only the active server address. If the active NTP server configured is IPv6, then distributing the IP address in the fabric will not be possible to switches earlier than Fabric OS v5.3.0 because IPv6 is supported for Fabric OS v5.3.0 and later. The default value LOCL will be distributed to switches earlier than Fabric OS v5.3.0. The tsClockServer command accepts multiple server addresses in IPv4, IPv6, or DNS name formats. When multiple NTP server addresses are passed, tsClockServer sets the first obtainable address as the active NTP server. The rest are stored as backup servers that can take over if the active NTP server fails. The Principal or Primary switch synchronizes its time with the NTP server every 64 seconds. Setting the date 1. Log in to the switch using the default password (which is password). 2. Enter the date command, using the following syntax: date "mmddHHMMyy" The values are: • mm is the month; valid values are 01 through 12. • dd is the date; valid values are 01 through 31. • HH is the hour; valid values are 00 through 23. • MM is minutes; valid values are 00 through 59. • yy is the year; valid values are 00 through 99 (values greater than 69 are interpreted as 1970 through 1999, and values less than 70 are interpreted as 2000 through 2069). switch:admin> date Fri Sep 29 17:01:48 UTC 2007 switch:admin> date "0927123007" Thu Sep 27 12:30:00 UTC 2007 switch:admin> Setting time zones You must perform the procedure on all switches for which the time zone must be set. However, you only need to set the time zone once on each switch, because the value is written to nonvolatile memory. Use one of the two following procedures to set the time zone. The first procedure requires you to select the actual time zone and the second requires you to select the country location of the switch. The following procedure describes how to set the current time zone to Central Standard time using timezonename mode. Brocade 6505 Hardware Reference Manual 11 53-1002449-01
