Juniper and Cisco Commands

 

Here's a comparison of some commonly used Juniper and Cisco switch commands for basic configuration and management:

1. Entering Configuration Mode

  • Juniper:
    configure
  • Cisco:
    configure terminal

2. Setting Hostname

  • Juniper:
    sql
    set system host-name <hostname>
  • Cisco:
    php
    hostname <hostname>

3. Saving Configuration

  • Juniper:
    sql
    commit
  • Cisco:
    arduino
    write memory
    or
    arduino
    copy running-config startup-config

4. Displaying Interface Information

  • Juniper:
    sql
    show interfaces
  • Cisco:
    kotlin
    show ip interface brief

5. Assigning IP Address to Interface

  • Juniper:
    csharp
    set interfaces <interface> unit 0 family inet address <ip-address>
  • Cisco:
    csharp
    interface <interface> ip address <ip-address> <subnet-mask>

6. Configuring VLAN

  • Juniper:
    python
    set vlans <vlan-name> vlan-id <vlan-id>
  • Cisco:
    php
    vlan <vlan-id> name <vlan-name>

7. Showing Running Configuration

  • Juniper:
    sql
    show configuration
  • Cisco:
    arduino
    show running-config

8. Checking VLAN Information

  • Juniper:
    sql
    show vlans
  • Cisco:
    sql
    show vlan brief

9. Setting Interface Description

  • Juniper:
    csharp
    set interfaces <interface> description <description>
  • Cisco:
    csharp
    interface <interface> description <description>

10. Rebooting the Switch

  • Juniper:
    perl
    request system reboot
  • Cisco:
    reload

Both Juniper and Cisco devices have their own syntax and structure. Juniper uses the JUNOS operating system with a hierarchy-based command structure, while Cisco uses IOS with a more linear configuration approach.

Here are more Juniper and Cisco switch commands for comparison:

11. Configuring a Trunk Port

  • Juniper:
    csharp
    set interfaces <interface> unit 0 family ethernet-switching port-mode trunk set interfaces <interface> unit 0 family ethernet-switching vlan members <vlan-id>
  • Cisco:
    csharp
    interface <interface> switchport mode trunk switchport trunk allowed vlan <vlan-id>

12. Configuring an Access Port

  • Juniper:
    csharp
    set interfaces <interface> unit 0 family ethernet-switching port-mode access set interfaces <interface> unit 0 family ethernet-switching vlan members <vlan-id>
  • Cisco:
    csharp
    interface <interface> switchport mode access switchport access vlan <vlan-id>

13. Enabling STP (Spanning Tree Protocol)

  • Juniper:
    csharp
    set protocols stp interface <interface>
  • Cisco:
    php
    spanning-tree mode <type> spanning-tree vlan <vlan-id> root primary

14. Viewing ARP Table

  • Juniper:
    sql
    show arp
  • Cisco:
    sql
    show ip arp

15. Enabling SSH

  • Juniper:
    sql
    set system services ssh
  • Cisco:
    ip ssh version 2

16. Configuring DHCP Relay

  • Juniper:
    csharp
    set forwarding-options helpers bootp relay-agent interface <interface>
  • Cisco:
    css
    ip helper-address <DHCP-server-IP>

17. Setting Static Route

  • Juniper:
    vbnet
    set routing-options static route <destination> next-hop <next-hop-IP>
  • Cisco:
    php
    ip route <destination> <subnet-mask> <next-hop-IP>

18. Configuring Link Aggregation (LACP)

  • Juniper:
    python
    set interfaces ae0 aggregated-ether-options lacp active set interfaces ae0 unit 0 family ethernet-switching vlan members <vlan-id>
  • Cisco:
    kotlin
    interface port-channel 1 switchport mode trunk channel-group 1 mode active

19. Enabling LLDP (Link Layer Discovery Protocol)

  • Juniper:
    csharp
    set protocols lldp interface <interface>
  • Cisco:
    arduino
    lldp run

20. Viewing Logs

  • Juniper:
    bash
    show log messages
  • Cisco:
    sql
    show logging

These commands provide more control over advanced configurations like trunking, STP, link aggregation, and protocols like LLDP and DHCP relay.

To configure DHCP protocol and SVI (Switched Virtual Interface) on both Juniper and Cisco switches, follow the steps below:

On Juniper Switch:

1. Configuring DHCP Server:

To configure the switch to act as a DHCP server:

csharp
set system services dhcp-local-server group <group-name> interface <interface-name> set access address-assignment pool <pool-name> family inet network <network-address>/<subnet-mask> set access address-assignment pool <pool-name> family inet range <range-name> low <low-ip> set access address-assignment pool <pool-name> family inet range <range-name> high <high-ip> set access address-assignment pool <pool-name> family inet dhcp-attributes router <gateway-ip>

Example:

sql
set system services dhcp-local-server group dhcp-group interface vlan.10 set access address-assignment pool dhcp-pool family inet network 192.168.10.0/24 set access address-assignment pool dhcp-pool family inet range range1 low 192.168.10.10 set access address-assignment pool dhcp-pool family inet range range1 high 192.168.10.100 set access address-assignment pool dhcp-pool family inet dhcp-attributes router 192.168.10.1

2. Configuring SVI:

To create a VLAN interface (SVI) and assign an IP address:

php
set interfaces vlan unit <vlan-id> family inet address <ip-address>/<subnet-mask> set vlans <vlan-name> vlan-id <vlan-id> l3-interface vlan.<vlan-id>

Example:

kotlin
set interfaces vlan unit 10 family inet address 192.168.10.1/24 set vlans sales vlan-id 10 l3-interface vlan.10

On Cisco Switch:

1. Configuring DHCP Server:

To configure a Cisco switch to act as a DHCP server:

php
ip dhcp pool <pool-name> network <network-address> <subnet-mask> default-router <gateway-ip> dns-server <dns-server-ip>

Example:

arduino
ip dhcp pool Sales network 192.168.10.0 255.255.255.0 default-router 192.168.10.1 dns-server 8.8.8.8

2. Configuring SVI:

To configure an SVI for inter-VLAN routing:

csharp
interface vlan <vlan-id> ip address <ip-address> <subnet-mask> no shutdown

Example:

kotlin
interface vlan 10 ip address 192.168.10.1 255.255.255.0 no shutdown

DHCP Relay (If using external DHCP server):

  • Juniper:

    csharp
    set forwarding-options dhcp-relay server-group <group-name> <server-ip> set forwarding-options dhcp-relay group <group-name> interface <interface-name>
  • Cisco:

    csharp
    interface vlan <vlan-id> ip helper-address <dhcp-server-ip>

These configurations will enable a DHCP server on both Juniper and Cisco switches and allow inter-VLAN routing using SVI.

TCP/IP MODEL

  HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...

Types Of Attack in Network

Common Network Attacks Explained. 1. Overwhelming a Network (DoS/DDoS): Imagine a restaurant that's flooded with too many customers. In a DoS/DDoS attack: A website is overwhelmed with too much traffic. 2. Eavesdropping on Conversations (MitM): Imagine someone listening in on your phone call. In a MitM attack: An attacker listens to your online conversations. 3. Tricking You (Phishing): Imagine receiving a fake email from your bank. In phishing: Attackers try to trick you into giving them your personal information. 4. Finding a Weakness in a Website (SQL Injection): Imagine finding a hole in a fence. In an SQL injection attack: An attacker finds a weakness in a website to steal or change data. 5. Planting a Hidden Camera (XSS): Imagine someone hiding a camera in a party. In an XSS attack: An attacker hides harmful code on a website to spy on you. 6. Guessing Your Password (Password Attck): Imagine trying to guess a friend's password. In a pas...
