lets talk about cisco switch fundamentals :

Adding an IP to the switch and not wasting a port .
_______________________________________
                        enable
                        conf term
                        int vlan1
                        ip addre 10.196.205.5 255.255.255.255
                        no shutdown
                        exit
                        ip default gateway 10.196.205.1
____________exit ______________________________


Removing an IP from a switch
enable
conf ter
int vlan 1
no ip addr
exit



configuring Interfaces and ports
enable
conf ter
int f0/0
duplex full ( also can be auto , half )
speed auto
spanning-tree portfast (use this only if connected to a server or workstation  , it disables spanning tree protocol )

and one can also use

int range f0/0-10 for configuring multiple ports at a time .

one can also use the following shell script

> i=1;while [ $i -lt 25 ]; do echo "int fast0/$i"; echo speed auto; echo duplex auto; echo span portfast; let i+=1; done;

DAG ...

finally today I got a chance to configure DAG exchange 2010 on a live environment  , nailed it . Though was on the call with microsoft for over 2 hrs but it was easy , it was just we being too chary , as we had no window for errors as running late already and the management is a little pissed ... but whatever it was good.

  a good detailed explanation tomorrow.

Disaster Recovery is the buzz word . It was real costly and had lotta overheads till ystrday but now whatever softwares are being roll out DR is considered a core requirement . Same applies to exchange 2010 , apart from being more efficient and having like a million new gems it has also got a DR option . Well I am in a team and will be working on it soon . so I will keep all posted.

prerequisites : need to know somethin about what all has happned.

changing the logon screen .

i was asked to change the logon screen i had no clue how to do it ... change the logon screen on Terminal Server , tat sounded easy but with the limited permissions I had it got so difficult .

well just have to remember that change the file in system32\oobe\info\backgrounds
add a file backgroundDefaul.jpeg... and yes it should be a jpeg file less than 256k ...
quiet possible that info\background might not exist so go ahead create one ...and dont fear changing the background.bmp file .

if not then also change the following registry entry

hklm\software\microsoft\window\currentversion\authentication\logonUI\Background

and change the OEMbackground to 0 ...

have been out of touch for quiet some time but m back with a bang .. actually to bang my head .. now onwards the blogs would not be about me but the type of technologies I workon ..... so here we go .... hit it ..


oh .. and so that you kno we will mostly be talking about Vmware , MS servers and switches .
