Use the super terminal software of the PC to access the vro and set the IP address of the vro to 10.32.10.32 and the IP address of the computer to the same network segment ). We recommend that you back up the original IOS files before performing the IOS upgrade to prevent problems with the IOS files to be upgraded from being unavailable;

The Cisco router sets IOS to upgrade each other. My company's network department has a Cisco router 2501, but IOS is bad. Here I call it cisocB, and another 2501 router IOS is good, we prefer ciscoA. Good IOS is no longer available on my PC, but it is transferred to the PC through TFTP on the PC, it would be a waste of time to upload it to the bad one ,. Then I thought of a way to directly configure the vro as a TFTP server.My connection method is that the two routers are connected through the E

XML query in SQL SERVER: FOR XML specifies AUTO
Preface
In SQL SERVER, you can specify RAW, AUTO, EXPLICIT, and PATH for XML queries. This article uses some examples to introduce the XML query of AUTO in SQL SERVER.
Basic example Section 1:
With TestXmlAs(Select 1 as id, N 'leewhoeeuniversity 'as nameUnion allSelect 2, N 'depop'Union allSelect 3, null)Select id, name from testxml for xml auto
Result:
Use the table name as the element name, which replaces the "row" in raw mode ".

Part 1:
With TestXmlAs(Select 1 as id, N 'leewhoeeuniversity 'as nameUnion allSelect 2, N 'depop'Union allSelect 3, null)Select id, name from testxml for xml auto

: 0Actual data bytes: 25556632 actual data bytes: 0Rexmt data pkts: 1605 rexmt data pkts: 0Rexmt data bytes: 2188780 rexmt data bytes: 0
Calculate the broadcast rate:Rexmt/actual * 100 = Retransmission rate
1605/18695*100 = 8.5%
The reason for this slow connection is that it has a broadcast rate of 8.5%.

First, log on to the vro using the Super Terminal and set the fa0/1 IP address.
R1 (config-if) # ip address 192.168.1.1 255.255.255.0

Set the IP address of the tftp server to 192.168.1.2/24
The IOS of the router is backed up to the tftp server.
In privileged mode, enter the command copy flash tftp and press Enter. after entering the address or Host Name of the tftp server and the file name to be copied, IOS will be backed up to the tftp server. The detailed command

The algorithm:
Just judge it. but you must read the problem seriously. espcially when you judge the status of WA and PE. that is, the numberic, you must compare all the number at the same time, do not one line each time. or else, you will get a wa like me.
