QoS CAR rate policies for MAC address on Cisco

Here is advanced example implement CAR rate policies for MAC address.

#### Define mac address in access-list

IOS(config)#
 access-list rate-limit 100 ca01.0412.0039
end

IOS#show access-list rate-limit 100
Rate-limit access list 100
    CA01.0412.0039

#### Set CAR rate policies for 1 Mbps or 1024 Kbps & Apply to interface

IOS(config-if)#
interface FastEthernet1/1
 description To-Router
 ip address 192.168.100.1 255.255.255.0
 rate-limit input access-group rate-limit 100 1024000 128000 128000 conform-action transmit exceed-action drop

#### Verify CAR

IOS#show interfaces FastEthernet1/1 rate-limit
FastEthernet1/1 To-Router
  Input
    matches: access-group rate-limit 100
      params:  1024000 bps, 128000 limit, 128000 extended limit
      conformed 0 packets, 0 bytes; action: transmit
      exceeded 0 packets, 0 bytes; action: drop
      last packet: 1497096ms ago, current burst: 0 bytes
      last cleared 00:02:14 ago, conformed 0 bps, exceeded 0 bps

Set Date Time on JunOS (Juniper Operating Sytem)

This intruction of set date time on JunOS.

#### Set Manual Date Time August 4, 2013 and 07:30:00 PM.
user@JunOS> set date ?
Possible completions:
 
  ntp                  Set system date and time using Network Time Protocol servers
  
user@JunOS> set date 201308041930.00 
Sun Aug  4 19:30:00 UTC 2013


#### Set Auto Date from NTP server
user@JunOS> set date ntp ?
Possible completions:
  <[Enter]>            Execute this command
             IP addresses of NTP servers
  source-address       Source address to use
  |                    Pipe through a command

#### Failed  
user@JunOS> set date ntp 192.168.0.1 
 4 Aug 19:01:05 ntpdate[4562]: no server suitable for synchronization found

#### Success
user@JunOS> set date ntp 192.168.0.2  
 4 Aug 19:30:34 ntpdate[4571]: step time server 192.168.0.2 offset -38185.458839 sec


#### Verify 
user@JunOS> show system uptime 
Current time: 2013-08-04 19:31:20 UTC

Set QoS CAR on Juniper

Previous posting about set CAR on Cisco, Another example for Juniper.

#### Set CAR rate policies for 1 Mbps or 1024 Kbps

set firewall policer Set-1M if-exceeding bandwidth-limit 1024000
set firewall policer Set-1M if-exceeding burst-size-limit 128k
set firewall policer Set-1M then discard

#### Set CAR rate policies for 4 Mbps or 4096 Kbps

set firewall policer Set-4M if-exceeding bandwidth-limit 4096000
set firewall policer Set-4M if-exceeding burst-size-limit 512k
set firewall policer Set-4M then discard

#### Create filter with rate policies

set firewall filter Car-1M term To-Router-1M then policer Set-1M
set firewall filter Car-1M term To-Router-1M then accept

After set CAR rate policies and filter, apply filter to interface?

#### Apply CAR to interface

set interfaces ge-1/0/0 unit 0 description "To-Router"
set interfaces ge-1/0/0 unit 0 family inet filter input Car-1M
set interfaces ge-1/0/0 unit 0 family inet filter output Car-1M
set interfaces ge-1/0/0 unit 0 family inet address 192.168.100.1/30

#### Verify filter (add count parameter)

[edit]
user@JunOS# set firewall filter Car-1M term To-Router-1M then count Car-1M

user@JunOS> show firewall filter Car-1M counter Car-1M 


Filter: Car-1M                                                 

Counters:
Name                                                Bytes              Packets
Car-1M                                               3952                   58

user@JunOS> show firewall filter Car-1M counter Car-1M    


Filter: Car-1M                                                 

Counters:
Name                                                Bytes              Packets
Car-1M                                               4224                   62
