the scrape...

after having erased the switch block and the l2 switches (switch block; a pair of distribution switches that aggregate  access layer switches)  i wrote the command set on paper? and scraped the configs in one a time... it took about 20 minutes to get everything to a base config; ie passwords, vty's, domain, vtp tansparent, of course, trunks, access ports, vlans, ip addresses, svi's, etc... i won't bore you with those particulars as you should be there by now...

next step was to make all the trunks port channels... i opened 4 telnet sessions at once and scraped the below configs into each (not including the names) since i connect my nix box to dls1 using a single l3 interface, this procedure can be tricky as the channels come up; ie, lags, errdisable, crashing telnet connections, etc... i didn't lose a single telnet session, but po1 on dls1 went into errdisable... once i shut, no shut po1, all channels were good...  with a term server this would be less prone to error, no chance of a telnet disconnect...

this took about five minutes
