The Dell PowerConnect 5548 switch with firmware 18.104.22.168 does not work with auto negotiate enabled on some Mac and other NICs.
The issue seems to be with the support for Green Ethernet. Here is the fix that worked for me:
5548-SW01(config)# no eee enable
As soon as commiting the change, the interface for the Mac systems came online.
The Mac ethernet ports need to be set to manual in order to access the switch without making the “no eee enable” config change.Read More...

For some reasons, you may want to modify the TTL (Time to Live) of a DNS Server.
The default TTL is 10800 seconds (3 hours). To modify the TTL, edit the following file on your OS X DNS Server and replace $TTL 10800 with the $TTL value you desire. Please note using a TTL value of 0 (zero) is not supported by some systems and is not advised.
The DNS cache on the client systems may need to be flushed to honor the new TTL. This is done on OS X by using the “dscacheutil -flush” command.
Here is an example config file:
dns1:~ root# cat /var/named/zones/db.cloudmac.net.zone.apple ;GUID=D521C96D-AA85-4438-A1BC-8B1D7987DCD0 ;selfResolvingHostname=0 $TTL 300 cloudmac.net. IN SOA dns.cloudmac.net. netopps.cloudmac.net. ( 2011112804 ;Serial 86400 ;Refresh 3600 ;Retry 604800 ;Expire 345600 ;Negative caching TTL ) cloudmac.net. IN NS dns.cloudmac.net. dns1 IN A 10.22.100.30 mail IN A 10.22.100.31 cloudmac.net. IN MX 0 mail.cloudmac.net. dns1:~ root#
Run the dig command to confirm the TTL information reflects what you entered:
dns1:~ root# dig mail.cloudmac.net @10.22.100.30 ; <<>> DiG 9.6-ESV-R4-P3 <<>> mail.cloudmac.net @10.22.100.30 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 983 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;mail.cloudmac.net.
