![]() cross ( px_Ah, p1_Ah ) lx2_A = ( lx2_Ah / lx2_Ah ) lx1_A = ( lx1_Ah / lx1_Ah ) # second orthogonal pair, 2z & xy The following code calculate the homography from the affine image to similar image. ![]() Notice that the perpendicular lines (in real life) are not perpendicular in the image. The image illustrates the measurement results. text ( * p, n, color = 'r', fontsize = 24 ) plt. scatter ( * p, color = 'r', marker = 'o', lw = 2, s = 42 ) plt. array ( for p in points_A ]) px_Ah, p1_Ah, p2_Ah, p3_Ah, py_Ah, pz_Ah = points_A names_A = for p, n in zip ( points_A, names_A ): plt. hstack (( x, 1 )), points )) points_A = np. The line connecting point 1 and point 3 ($\mathbf$), which will be used to recorve the information about parallel lines in the image.

(BTW, another time I had an issue, I had already erased the running IOS image THEN I discovered the system wouldn't load any IOS.Px, p1, p2, p3, py, pz = np. Often such was cured by reloading the device even with its existing IOS. ![]() Lastly, I have encountered "sick" Cisco devices, those that wouldn't load using tftp. (NB: I once had a new image reload fail because I didn't check.) Of course, before reloading, insure your newly loaded image is a "good" copy (by doing a image verification check). ![]() Sometimes I've found "old" minimal IOS images will fit on flash with the newer image - useful, again, if a new IOS image fails for some reason.īTW, I've very rarely had an issue loading an IOS image after erasing the existing image from flash. (NB: don't forget other Cisco devices, including 3750s, can be tftp servers.) If you get "stuck" with a non-bootable 3750, as Seb mentions, you can then use XMODEM to load a new image.īesides falling back to XMODEM, if you have any other host, that can support tftp, on a shared network that the 3750s is on, you can use it to deal with a botched load. (NB: some of the early 3750s also don't have enough flash to run a 15.x image.) That's not uncommon, the need to remove an existing IOS image, before loading a newer image (at least on earlier devices that often didn't have sufficient flash to contain more than one IOS image. Join-window Configure time interval to enable directorĪny ideas how we can disable vstack on these models please ? Hostname-prefix Specify hostname prefix for Client End with CNTL/Z.Ĭonfig - Configure default configuration fileĭhcp-localserver Configure vstack dhcp parametersĭirector - Configure director's IP address I have tried few of the followings but vstack was still enabled and port 4786 is still listening.Įnter configuration commands, one per line. On these 3750s ' No Vstack ' command is unavailable. *** Following configurations will be effective only on director *** To fix recent vulnerability with smart install ( ) we have been disabling vstack on all our switches as we dont use this feature. We have this C3750 switches on our network with IOS version - 12.2(55)SE1.
