I'm reading the SWITCH OCG for the second time now, and I noticed page 210 is completely missing: it's a duplicate of page 212. I'm still wondering why I didn't see it the first time I read it.

View 1 Replies View RelatedI am currently working on an example for a CCNP Spanning Tree Protocol example.I have some lectures on video and getting confused with an example they have provided. It has me baffled as I have compared it against numerous other websites, trawled forums and tried to get other examples to compare it against.Anyway, I have posted screenshots of the topology. They are as follows:
1) topology showing links so can assign costs (100mbps = STP cost 19, 1000mbps = STP cost 4)
2) topology show priority and MAC addresses (priority left at default so root bridge elected by lowest MAC address)
3) topology showing elected root ports **which I do not agree with for switches E & F**
4) topology showing subsequent blocked ports **which I do not agree with for switches D & F, even if I accepted the previous given root port election*** I understand for same cost paths to root bridge that lowest bridge ID wins. So here are my queries:
1) switch E has 2 equal cost paths to root bridge (A):
-via: E > D > A (4 + 19)
-via: E > C > A (4 + 19)
so I think pick the next hop switch with lower bridge ID. Switch C right? In this example it says pick port going to switch D. I am confused! Why pick port going toward switch D?
2) switch F has 2 equal cost paths to root bridge (A):
-via: F > C > A (4 + 19)
-via: F > D > A (4 + 19)
so I think pick the next hop switch with lower bridge ID. Switch C right? In this example it says pick port going to switch D. I am confused! Why pick port going toward switch? tell if the example in the diagram (topology 3) is wrong? If it is correct explain why?Now on to issue number 2...If I accept the root port election given in the topology, I go through the process of assigning designated ports and blocked ports.I understand for each link there is at least 1 designated port. If it is a redundant link, one side will be designated, one side blocked. The designated port will be on the side of the lowest bridge ID (priority + MAC address). So here are my queries:
1) there is a redundant link between switch C and switch F
-one side must be designated
-one side must be blocked
-pick the side with lowest bridge ID (priority + MAC address) for designated port
-switch C has same priority as switch F, so based off MAC address, switch C wins i.e. designated port on switch C side, blocked port switch F side.
-In this example it says port from switch C is blocked and port from switch F designated. I am confused! Why pick port going from switch F as designated?
2) there is a redundant link between switch D and switch C
-one side must be designated
-one side must be blocked
-pick the side with lowest bridge ID (priority + MAC address) for designated port
-switch C has same priority as switch D, so based off MAC address, switch C wins i.e. designated port on switch C side, blocked port switch D side.
-In this example it says port from switch C is blocked and port from switch D designated. I am confused! Why pick port going from switch D as designated?
I'm looking to sit the ICND2 exam soon and have discovered that the pair of old 2924XL switches are not going to cut the mustard for the newer vlan commands and other features.
Would a pair of WS-C3550-24-SMI switches be a sensible replacement for ICND2 and possibly up to CCNP? They are available on ebay for about £80 each.
We had an power shutdown activity last week, due to which one of the core switch was turned off and ON .After the core switch was turned ON, we had found some of the ACLs missing which were bounded in VLANs. We had given write command before this power shutdown activity.We need to find the root cause for the same.
Switch Model-WS-CISCO-6509-E.

View 7 Replies View RelatedI have a strange problem with one switch in my LMS 3.2.1 installation.It is a WS-C3560-48TS with IOS 12.2(50)SE3 running. I have nine switches with the same type and IOS running without problems.
I notice the problem because there were no UT data for that switch. In RME and CS it was managed.Checking SNMP and config of the switch, but can't find any issues.Because at this time LMS ran in version 3.2 I installed at first CM 5.2.1 and after that the patches for CSCtd49439 and CSCtg20882.Next step was RME 4.3.1 with a lot of patches for different issues. Then I installed the patch for the internal error of CS (CSCtd07131).And finally I installed LMS 3.2.1 and patch for CSCto46927.Last step was installing the latest device packages. I did this directly from the application because it is much better handling than do a manual download. No the system seems to be fully updated.
I had the hope that CM will now find and manage this one switch. But it is still not available.I can't find the device in the data collection. But I can find it in the "Include Devices From DCR", although I configured to fetch all devices from DCR automatically to CM. To manually include the device is not working, too.
P.S. I used that step-by-step update path because it worked on two other servers very well for me.
I'm reading the CCNA Sec book (554) and I've just finished a few chapters on CCP.Is the tool free? Can it be simulated in PT, or emulated in GNS3? Speaking of which, can the entire CCNA/CCNP Sec track be emulated in GNS3?

View 2 Replies View Related We use all Cisco router in our business mostly 1841 and 871. But now i'm currently working with a new router:
Just purchased last week - Cisco 881
The Cisco IOS is:
Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version 15.0(1)M6, RELEASE SOFTWARE (fc1)
->System image file is "flash:c880data-universalk9-mz.150-1.M6.bin"
As all our router are Cisco we use EIGRP as our routing protocal. But with this router all I see is:
#router ?
odr On Demand stub Routes
rip Routing Information Protocol (RIP)
Where is my EIGRP ? I can't configure eigrp, so my router wont be doing much routing.
I recently moved to another room as I was removing my router I removed some tape unbeknown to me it also removed my MAC Number. Is there anyway I can recover that Mac Number?

View 3 Replies View RelatedI have two 1841 routers running different IOS versions:R1 running 15.0(1)M3 Advanced IP ServicesR2 running 15.1(4)M2 Advanced IP Services R1 supports the encapsulation dot1q second-dot1q on FastEthernet subinterfaces. Surprisingly, R2 with the newer IOS (of the same feature set) does not have the second-dot1q command option. I've done my Feature Navigator homework but I did not see any significant differences between these two IOS versions that would explain why the second-dot1q command is not available on R2. Am I missing something? Has the syntax changed, or a different feature set is needed for 15.1M and higher to get the second-dot1q command back?

mls qos
mls qos map cos-dscp 0 8 16 40 32 46 48 56

shape-timer Set the HQF shape timer interval
The router is running IOS:
System image file is "flash:c2801-ipbasek9-mz.151-4.M5.bin"
Am i just running the incorrect IOS or am i missing somehting, i need to change the QoS Map for my Nortel VoIP. The VoIP phones connect to a 3750 PoE which used to conenct to a 2651XM to route VoIP and data traffic over the same copper pairs (WAN link to hub site) hence the need for a Service policy but being Nortel phones, require changing the cos-dscp map. the 2801 is going to replace the 2651XM using a new HWIC.

View 4 Replies View Relatedtoday I received a Cisco Router 881G with PCEX-3G-HSPA-G for a customer that ordered a Router with the feature to send/receive SMS and to remotely active the 3G Internet connection through SMS. I believe that the router that meets this requirement is the Router 881G that I received today. In particular, the model is:
CISCO881G-K9
Now, I installed the router and configured the 3G link that is working properly BUT all the commands related to the SMS are completely missing. In particular, I miss the command:
cellular gsm sms send
gsm sms archive path
In the following documentation I see that these commands should be available: [URL]The fact that these commands are missing sounds very strange to me since the documentation is pretty clear. Do I need to activate any license? I also upgraded tha router to the last version...

My company is moving the datacenter to our new building on Saturday, however the users will remain at the old building until late next month so they bought a 100M Metro E VPLS circuit through their ISP. I went to test it today but could not ping the workstation from my laptop. I wanted to do some bandwidth testing with iperf but could never get to that point because ICMP connectivity wasn't even there. From what I understand, VPLS is just a layer 2 extension so they way I'm testing the circuit below SHOULD work, but it isn't. Spoke with the ISP and they tested the circuit end-to-end on their equipment which was fine so am I missing something?
