Hi, I can see from the spec of an SFP module it has a range of output power. How do i control that in the IOS or does it do it automatically based on rx power level?I know there is 'show interface tranceiver' to show me whats happening but not sure h...
Hi all, is it OK to point a Windows 2003 server at a HSRP address for its Windows time address? I once heard there were bugs in doing this, can someone confirm this?Clearly my router is acting as a client/server, getting its time from our core netwo...

Thanks for the replies. My 'ntp' clients is actually the Windows Time service. The reason I wated to use the HSRP is because from Windows clock GUI you can only specify one target address. I think it may be possible to put multiple addresses via t...
