1. 0:00all right welcome back its back to the
2. 0:01basics I am Sean bar and today we are
3. 0:04talking out of bed management everything
4. 0:07from console ports to see Mac let's go
5. 0:10[Music]
6. 0:22alright welcome back and we are talking
7. 0:24out of band management so if you're
8. 0:27managing network infrastructure it is
9. 0:30really or any infrastructure for that
10. 0:32matter out of band management may be key
11. 0:35to saving you from driving down to the
12. 0:38data center at 2:00 in the morning to
13. 0:40fix a server or a network device or
14. 0:43maybe it's not even drivable maybe you'd
15. 0:45have to get on a plane or call somebody
16. 0:47wake them up and drive men either way
17. 0:49out of band management can be a
18. 0:51lifesaver so what is out of band
19. 0:54management it's almost exactly what it
20. 0:57sounds like
21. 0:58so in band management would be going to
22. 1:00the IP address of a device may be
23. 1:02through SSH HTTP web browser ssh telnet
24. 1:06all those in band / RDP to a server
25. 1:11those are all forms of in band
26. 1:13management where you're going to the IP
27. 1:14of the actual device out of band
28. 1:17management for a networking device would
29. 1:20be through a console port and in order
30. 1:23to do that to get access to a console
31. 1:25port over a network you would need a
32. 1:29console server so there's a number of
33. 1:31console servers out there one popular
34. 1:34one is a cycloid console server where
35. 1:36you would take your critical core
36. 1:38infrastructure components and plug those
37. 1:40into a console server and maybe you'll
38. 1:42have an extra internet connection or
39. 1:44some of them even have LTE options where
40. 1:46you can have a mobile device in through
41. 1:49Wireless be able to connect into a
42. 1:51device a router switch a firewall to
43. 1:54make changes and a good example would be
44. 1:56if you're connected remotely to a
45. 1:58firewall and maybe you don't allow
46. 2:00management in band management through
47. 2:02the IP the public IP maybe you don't
48. 2:04allow management to that public IP
49. 2:06address so you're making some firewall
50. 2:09changes and you lock yourself out well
51. 2:11how do you get back in without somebody
52. 2:13being on site out of band management or
53. 2:16console server could help you in that
54. 2:18scenario and especially if it had some
55. 2:20out-of-band access to that console
56. 2:23server meaning another internet
57. 2:24connection maybe an MPLS connection or
58. 2:27like we mentioned LTE with servers
59. 2:31there's also out-of-band management with
60. 2:33those with Cisco there's their seeming
61. 2:36and with Dell its they've got their Drac
62. 2:38and with HP they've got their i lo and
63. 2:41so those are all out of band management
64. 2:43of the server and so what those can do
65. 2:46is they'll plug into a separate Ethernet
66. 2:48connection outside of the server so if
67. 2:50it dies you can get what's considered
68. 2:52KVM which is keyboard video and mouse
69. 2:55remotely and it gives you that same
70. 2:57experience as if you're sitting in front
71. 2:58of the server with a keyboard of videos
72. 3:02display a monitor and a mouse so you can
73. 3:05remotely manage that server even if it's
74. 3:07down or watch it boot up things like
75. 3:09that with those out-of-band management
76. 3:11tools
77. 3:12so to recap on this if you've got
78. 3:15servers sitting in a remote location or
79. 3:17any location you should really consider
80. 3:19leveraging their out-of-band management
81. 3:21and using an out-of-band management
82. 3:23network and maybe having a couple of
83. 3:25ways to get access to that out of band
84. 3:27management network if you've got
85. 3:29critical network infrastructure getting
86. 3:31a console server there's cycling there's
87. 3:32a number of others you plug in the
88. 3:34consoles into the you plug the console
89. 3:37server into the console port of each of
90. 3:39those critical infrastructure devices
91. 3:40make sure you've got multiple ways to
92. 3:43get to that console server whether it's
93. 3:45LTE a secondary internet connection an
94. 3:47MPLS connection and if you have those
95. 3:49issues at night you've got a way to get
96. 3:52in and not wake up drive to the office
97. 3:55or even worse call somebody in a remote
98. 3:57location and get them to drive to the
99. 3:59data center that can be brutal so we've
100. 4:01covered out a band management we cover
101. 4:03console servers we've covered I low
102. 4:05cement Mick Drac covered a lot if
103. 4:09there's anything I said in this video
104. 4:09that you want to know more make sure you
105. 4:12leave a comment if you liked it like
106. 4:14subscribe there's something you want us
107. 4:16to do we'll do it see you on the next
108. 4:19one thanks for watching
