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:

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.

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.

BRIDGE MODE AND NAT MODE AP

  BOTH BRIDGE MODE AND NAT MODE ARE WAYS TO CONFIGURE AN ACCESS POINT (AP) TO EXTEND A NETWORK, BUT THEY DIFFER IN HOW THEY HANDLE IP ADDRESSES AND NETWORK TRAFFIC: BRIDGE MODE: CONCEPT: ACTS AS A TRANSPARENT BRIDGE, SIMPLY RELAYING DATA BETWEEN WIRED AND WIRELESS DEVICES. IP ADDRESS: DEVICES OBTAIN THEIR IP ADDRESSES FROM AN UPSTREAM DHCP SERVER, TYPICALLY THE MAIN ROUTER ON THE NETWORK. NETWORK TRAFFIC: ALL DEVICES, BOTH WIRED AND WIRELESS, ARE SEEN AS PART OF THE SAME NETWORK AND CAN DIRECTLY COMMUNICATE WITH EACH OTHER. BENEFITS: SEAMLESS ROAMING: DEVICES CAN EFFORTLESSLY SWITCH BETWEEN APS WITHOUT LOSING THEIR IP ADDRESS OR CONNECTION. SIMPLIFIED NETWORK MANAGEMENT: ALL DEVICES ARE ON THE SAME SUBNET, MAKING CONFIGURATION AND TROUBLESHOOTING EASIER. INCREASED COMPATIBILITY: WORKS WITH DEVICES THAT DON'T SUPPORT NAT TRAVERSAL (E.G., SOME VPN CLIENTS). DRAWBACKS: LESS SECURITY : ALL DEVICES ARE DIRECTLY EXPOSED TO EACH OTHER, POTENTIALLY INCREAS

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once.

VSC (Virtual Cluster Switching)

  VIRTUAL CLUSTER SWITCHING (VCS): THIS IS A PROPRIETARY NETWORK FABRIC TECHNOLOGY DEVELOPED BY BROCADE, LATER ACQUIRED BY EXTREME NETWORKS. IT ALLOWS MULTIPLE PHYSICAL SWITCHES TO BE COMBINED AND MANAGED AS A SINGLE LOGICAL UNIT, OFFERING SEVERAL BENEFITS: SIMPLIFIED MANAGEMENT: MANAGE THE ENTIRE VCS AS ONE ENTITY, REDUCING CONFIGURATION OVERHEAD AND TROUBLESHOOTING COMPLEXITY. INCREASED PORT DENSITY: COMBINE PORTS FROM MULTIPLE SWITCHES TO CREATE A LARGER POOL OF AVAILABLE CONNECTIONS. IMPROVED PERFORMANCE:   ENHANCE LINK UTILIZATION AND LOAD BALANCING ACROSS MULTIPLE PHYSICAL LINKS, REDUCING BOTTLENECKS. ENHANCED REDUNDANCY:   PROVIDES FAILOVER PROTECTION IN CASE OF A SWITCH FAILURE. TRAFFIC WILL BE AUTOMATICALLY REROUTED TO OTHER SWITCHES WITHIN THE VCS. SIMPLIFIED NETWORK TOPOLOGY: ELIMINATES THE NEED FOR COMPLEX LINK AGGREGATION OR SPANNING TREE PROTOCOL (STP) CONFIGURATIONS. _________ VCS, OR VIRTUAL CLUSTER SWITCHING, CAN OPERATE IN DIFFERENT MODES DEPENDI
