WEBVTT 1 00:00.000 --> 00:04.680 All right, once again at the CLI and what we want to do here is we want to 2 00:04.680 --> 00:09.000 create a policy map that references the class maps that we created in the last 3 00:09.000 --> 00:09.000 section. 4 00:09.000 --> 00:14.000 So let's go ahead and do a policy map command. 5 00:14.000 --> 00:18.750 Do our question mark and we see we can specify a type again with iOS X E and 6 00:18.750 --> 00:20.000 standard MQC. 7 00:20.000 --> 00:21.000 We don't need to worry about the type. 8 00:21.000 --> 00:24.000 I'm just going to specify a name of CBT in this case. 9 00:24.000 --> 00:26.000 And now I'll use that class command. 10 00:26.000 --> 00:30.370 This allows me to specify a class map name of one I've created or again that WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 10 00:26.000 --> 00:30.370 This allows me to specify a class map name of one I've created or again that 11 00:30.370 --> 00:32.000 class default option. 12 00:32.000 --> 00:37.810 I'll use DSCP E F to create my queue that matches according to E F and I can 13 00:37.810 --> 00:40.000 specify the priority command here. 14 00:40.000 --> 00:42.000 Turn this into a priority queue. 15 00:42.000 --> 00:45.460 Now that question mark here, I could just hit enter and that will turn it into 16 00:45.460 --> 00:47.000 a strict priority queue. 17 00:47.000 --> 00:52.650 Usually that's not a good idea or I can specify some amount of bandwidth to 18 00:52.650 --> 00:55.000 reserve and not just reserve for it, 19 00:55.000 --> 00:59.000 but actually turn it into a limit when things are congested. 20 00:59.000 --> 01:04.370 So I love that it's kilobits here by the way, not just all one word, but either WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 20 00:59.000 --> 01:04.370 So I love that it's kilobits here by the way, not just all one word, but either 21 01:04.370 --> 01:07.000 way we could specify 100 kilobits 22 01:07.000 --> 01:12.000 and that would be maybe decent depending on the situation. 23 01:12.000 --> 01:15.000 So from here I can exit out and I can specify my next class. 24 01:15.000 --> 01:19.000 In this case, maybe I want to do DSCP E F for X. 25 01:19.000 --> 01:22.000 That would be that class that I defined as well. 26 01:22.000 --> 01:26.000 And then I could use the band with command. 27 01:26.000 --> 01:31.210 And same thing here, I've got kilobits per second so I could specify 50,000 to WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 27 01:26.000 --> 01:31.210 And same thing here, I've got kilobits per second so I could specify 50,000 to 28 01:31.210 --> 01:34.000 make it 50 megabits per second 29 01:34.000 --> 01:38.000 since 1000 kilobits turns into a megabit there. 30 01:38.000 --> 01:40.000 And so we've got that option. 31 01:40.000 --> 01:44.000 I can also do another class statement here, go to class default. 32 01:44.000 --> 01:48.350 And even though we didn't configure class default with a class map, again it's 33 01:48.350 --> 01:49.000 system configured. 34 01:49.000 --> 01:52.610 I can run a question mark here, I can see my options, I could enable that fair 35 01:52.610 --> 01:53.000 queue. 36 01:53.000 --> 01:55.000 So that's not a bad idea in class default. 37 01:55.000 --> 01:59.000 I might also want to give it a bandwidth reservation. 38 01:59.000 --> 02:05.000 Maybe I want something like bandwidth percent and then we can specify 25 here. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 38 01:59.000 --> 02:05.000 Maybe I want something like bandwidth percent and then we can specify 25 here. 39 02:05.000 --> 02:08.000 So I'm going to reserve 25% of the bandwidth. 40 02:08.000 --> 02:09.000 Oh, that's right. 41 02:09.000 --> 02:15.000 I forgot I already specified a hard bandwidth of 50 megabits per second. 42 02:15.000 --> 02:16.000 We can't mix and match those. 43 02:16.000 --> 02:20.400 So yeah, that would be an option that we could use if we had used percent 44 02:20.400 --> 02:21.000 earlier. 45 02:21.000 --> 02:24.000 Instead, we'd have to calculate it ourselves. 46 02:24.000 --> 02:29.030 So maybe it's a gig link and I don't want to reserve 250 megabits per second 47 02:29.030 --> 02:30.000 for that gig link. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 48 02:30.000 --> 02:31.000 So there we go. 49 02:31.000 --> 02:33.000 That would be a policy map configuration. 50 02:33.000 --> 02:36.000 Now all we need to do is apply it to an interface. 51 02:36.000 --> 02:38.000 Let's get on to interface gig one zero. 52 02:38.000 --> 02:42.000 And the way we do this is with the again service policy command. 53 02:42.000 --> 02:43.000 Do a question mark. 54 02:43.000 --> 02:45.000 We see we have input and output. 55 02:45.000 --> 02:47.000 Usually we're talking about output. 56 02:47.000 --> 02:50.000 Now I specify the name CBT and I hit enter. 57 02:50.000 --> 02:55.000 Now I want to show a very powerful verification command, which is very useful 58 02:55.000 --> 02:56.000 for not only 59 02:56.000 --> 03:00.000 verifying configurations, but also in trying to troubleshoot some issues. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 60 03:00.000 --> 03:07.000 We can do show policy map interface and then specify our interface name. 61 03:07.000 --> 03:09.000 This is a wonderful command. 62 03:09.000 --> 03:12.000 It has served me wonderfully over the years. 63 03:12.000 --> 03:16.000 I highly recommend getting in mind to use this. 64 03:16.000 --> 03:20.350 So there's all kinds of show commands that we might get distracted by that 65 03:20.350 --> 03:24.000 might be trying to show what we think is configured, all these various things. 66 03:24.000 --> 03:28.040 This shows us not only what's actually configured on the interface in terms of 67 03:28.040 --> 03:32.880 the various cues, but it even shows us how many packets were received with a WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 67 03:28.040 --> 03:32.880 the various cues, but it even shows us how many packets were received with a 68 03:32.880 --> 03:34.000 particular tag. 69 03:34.000 --> 03:37.620 So we can make sure our cues are working by going and generating traffic that 70 03:37.620 --> 03:39.000 uses some of these tags. 71 03:39.000 --> 03:44.040 Maybe make sure that, yeah, I think this is going to match AF41 or 42 or 43, 72 03:44.040 --> 03:48.000 but maybe I forgot to make it match any instead of match all. 73 03:48.000 --> 03:52.670 And then my packets are landing here in class default, so that wouldn't be good 74 03:52.670 --> 03:53.000 . 75 03:53.000 --> 03:56.000 But we do see that we've got a lot of options here. 76 03:56.000 --> 04:01.000 We see that it does clarify that the priority classes are listed separate. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 76 03:56.000 --> 04:01.000 We see that it does clarify that the priority classes are listed separate. 77 04:01.000 --> 04:03.000 So I can see the priority class up here. 78 04:03.000 --> 04:05.000 I can see the rest of them down below. 79 04:05.000 --> 04:09.000 Very, very powerful command that show policy map interface. 80 04:09.000 --> 04:11.000 So let's keep that in mind as well as we move forward.
