Hi,All
Hope you are well I got warning on my router console do u know what is that?
I am sharing cause of it issue with memory
"*Dec 29 06:51:46.077: %C2600-4-SMARTINITDISABLE: Warning! You have disabled SMART INIT
and manually configured the amount of IO memory allocated. This is HIGHLY
discouraged on the Cisco 2600XM Series platforms as it may deprive the
system of memory necessary for normal operation. It is highly recommended
that SMART INIT not be disabled to ensure proper router operation."
I got this warning message when i reboot my router or i comes automatically on my router console after upgrading IOS image!!!
Well Well... It just warning but very important we have to consider it.
it comes usually cause of following reason!!
(1)If we set IOMSET in rommo mode : iomemset percentages
Ref link : http://www.cisco.com/en/US/docs/routers/access/1800/1841/software/configuration/guide/b_rommon.html#wp1069508
(2)If we are install wrong IOS image on platform (example 2600XM image running on non-2600XM model)
Hope when next time these error comes you can troubleshoot
Regards,
Jignesh

Archive
Hi..
I posting something interesting you most of time seen in show run command in router output but you never take attention it is nothing but just archive. Are you heard!!
Archive attributes in window set when new file created or after backup process it changes. So same in router for configuration files why not!!! Do you think for it. I think no but i suddenly see and got idea!!! so Well Shall We start...
Archive used to regularly for backup process for router configurations. In that you can create multiple archives. you can verify using "R#show archive" commands.
:Configurations:
R#config t
R(config)#ip ftp username JIGNESH
R(config)#ip ftp password CISCO
R(config)#archive
R(config-archive)#path ftp://192.168.1.1/r-config
R(config-archive)#write memory
R(config-archive)#time-period 1440
In this we can also do for TFTP server, in that you not need username and password.
Thank you,

NSSA Area In OSPF
Dear All.
Hi.. I am posting Not-So Stub Area in OSPF configurations.It is often time used when our ASBR router in not on backbone areas or we are redistributing different Routing protocol with ordinary areas(Not back-bone area).
Redistribution into NSSA create special-type of link in OSPF. In NSSA-ASBR router generate LSA-7 and NSSA-ABR router converted into LSA-5. Here In NSSA Area LSA-4 and LSA-5 are blocked but allowed LSA-3, In totally NSSA stub area allowed only summary route.
It is very carefully care when you plan for NSSA area in OSPF domain.
Please See below Figure First and Check Configurations.

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.

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

NNI-FRS network(SVC and PVC)
Hello!!
Here I post something new in frame-relay for me today i learn. It is just NNI protocols that route frame relay frame between switches to switches.
NNI means Network-to-Network Interface protocol.
In Frame Relay Three types of mainly interfaces available
(1) DTE- Data Terminal Equipement
(2) DCE- Data Communication Equipement
(3) NNI- Network-to-Network Interface
Here below you See Image.
Now See Configurations

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
!
ip hostname TERMIANLSERVER
!
ip domain-name CISCO.COM
!
ip host BANGLORE_CY 2001 1.1.1.1
ip host CHENNAI_JN 2002 1.1.1.1
ip host TIRUPATI_CE 2003 1.1.1.1
!-- Here you configured up to 16 lines
!
interface loopback 1
ip address 1.1.1.1 255.255.255.255.255
!
ip default-gateway
!-- When Routing Fail, it is booting ROMMO MODE so configured
!
line con 0
transport input all
line 1-16
session-timeout 20
!
!
line aux 0
transport preferred telnet
transport input all
speed 38400

Hi!!
I Got Learn something new today in EIGRP troubleshooting it's BFD-Bidirectional Forward Detection. it is protocol that design by cisco based of IETF.
This detection accomplish via Hardware detection mechanism, signal from mechanism are not always conveyed direct upper layer protocols.
Protocol detection failure is slower, Usually timer more than one minute. but BFD detect failure rapidly and of course maintain low overhead on link.
BFD- (transmit Interval) * ( detect multiplier) = Detect Timer
Where,
Interval:- Determine how frequency (milliseconds) BFD packet sent.
Min_RX:- Determine how frequency (milliseconds)BFD packet received from neighbors.
Multiplier :- The number of consecutive BFD packet which are missed from BFD peers before declaring dead or informing higher level protocol for failure.
********Configuration********
!
[no] bfd interval <50-999> min_rx <1-999> multiplier <3-50>
!
router eigrp 123
bfd all-interface
or
!
router eigrp 123
bfd interface serial 1/0
!
show bfd neighbor [details]

Thank you,
