期望脚本：中断和成功连接都返回EOF

Question

我试图将一组命令推送到思科设备。最后一个命令显然是＆＃34;退出＆＃34;。

如何确定两者之间的差异，因为可以通过eof跟踪它们。

1. 所有命令都已成功推送。
2. 由于网络连接丢失，连接在执行命令时被中断。

我目前正在使用expect_after/expect_before来抓住eof。

这里是虚拟命令集：

!test
!test
!test
!test
!test
!test
!LAST!!!!
exit

My expect_before statement:

expect_before {
    eof {
        RGenerateLog "${logdir}sendconfig-error.log" "${logprefix} Connection was interrupted."
        exit 11
    }
}

SCENARIO 1 (Successful):

sw05-00-00-2960.1194.POE#!test
sw05-00-00-2960.1194.POE#!test
sw05-00-00-2960.1194.POE#!test
sw05-00-00-2960.1194.POE#!test
sw05-00-00-2960.1194.POE#!test
sw05-00-00-2960.1194.POE#!test
sw05-00-00-2960.1194.POE#!LAST!!!!
sw05-00-00-2960.1194.POE#exit
Connection closed by foreign host.

Log:
2015-05-27 12:32:13 [cisco.exp]: User=XXXXXXXX; Device=10.218.8.199; Action=config_change - Connection was interrupted.

SCENARIO 2 (Interrupted - I've closed the connection explicitly in the firewall):

sw05-00-00-2960.1194.POE#
sw05-00-00-2960.1194.POE#Connection closed by foreign host.
[root@tritone /tritone/system/send-config]# 

2015-05-27 12:35:40 [cisco.exp]: User=XXXXXXXX; Device=10.218.8.199; Action=config_change - Connection was interrupted

所以我的问题是，如何成功推送所有命令，我怎么知道？
