Aux Port with Cisco router

Dear All
I post today morning to connect your router with Aux port. To connect Aux port you need modem that support DB-25 Connector to RJ-45(Rollover) cable.
See Below Image Carefully And Remember Points:



Remember Following Points


(1)The AUX port on Cisco routers is either RJ−45 or DB−25. If the AUX port is RJ−45, use a flat−satin rolled RJ−45−−RJ−45 cable (part number CAB−500RJ= ), which is usually provided with every Cisco router for console connections. You also need an RJ−45 to DB−25 adapter marked "MODEM" (part number CAB−25AS−MMOD) to connect the rolled cable tothe DB−25 port on the modem.
(2)If your router has a DB−25 AUX port, use a straight−through DB−25Female − DB25Male
RS−232 cable to connect the modem to the router.

For more information on cabling, see Modem−Router Connection Guide and Cabling Guide
for RJ−45 Console and AUX Ports

Check AUX lines First.
Now Plan to configure Aux line on router to connect with Terminal.

Router(config-line)#modem inout
Router(config-line)#speed 115200
Router(config-line)#transport input all

Terminal Server 2511 with Octale cable

Hi..

Today I post you some Important to Access Routers Using Terminal Server with Help of Octal Cables. This is most probably seen in Lab environment to Access your CCNP or CCIE racks.
So Lets Start Please Seen Image First!!




Now Here We Connect our terminal Server using Aux or Console port. Terminal Server 2511 series route with Async ports. Octale Cable have lines 1-8 and 9-16.

you have just physically connect 2511 router with other router using octale cable in console first.

Router 2511 Configurations

Implementaions ACL

Friends!!!
We are now implementing ACL.






In this Fig We block some address range in internal networks to access web server using ACL

Router(config)#access-list 101 deny 192.168.1.0 0.0.0.15 host 10.1.1.1 eq www
Router(config)#access-list 101 permit any any
Router(config)#interface F0/1
Router(config-if)access-group 101 in
Router(config-if)#exit

Here First statement of ACL 101 indicate block some range in internal network in example it will be 0-15 host on network 192.168.1.0 it will be deny for web server.
except this all are allowed to access web server.


Thank you,

ACL Fundamentals

Hello Friends!!!
ACL stands for ACL-Access Control List, list of statements which matched with packets and check condition for allow or block packets towards destination.

Types Of ACL : Standard & Extended ACL

Standard ACL check only source address of packet and take decision it could not check whatever destination and which applications (port no).

Extended ACL check source address, destination address, protocol, and port numbers.

Number Allocated to ACLs: (1) Standard ACL (0-99, 1300-1999)
(2) Extended ACL (100-199, 2000-2699)


Before Implementing ACL on routers we have to clear about inbound and outbound interface:

Inbound: check packet before entering packets
Inbound method apply on interface then we first check packet before packet goes to routing!!! easy...

Outbound: check packet before leaving interface
Outbound method apply on interface then first go to routing table check route and check ACL for allow or deny.

Wildcard Mask: Reverse of Subnet mask in we match and don't match of bits. Here 0 means must match and 1's means don't match.
e.g 10.23.23.0 0.0.0.255 means first three octant matched last one not required.

For more detail and implementaion I put blog in next blog..

Thank You,
