Comment on Use MRTG to monitor bandwidth by Fabio Semperboni

Hi,
I don’t think that there is the auto update feature. For an access switch you could simply monitor all interface..

No, the interface on each sides must be the same: L2 – L2 or L3 – L3

Or you could enable directed broadcast on the vlan the PC is on and just do a port forward to the broadcast address.

That way you don’t have to add static arps for every PC.

Hi,

I was successfully configured it. However, it looks like it won’t auto update when there is new ports add or deleted in the cisco switch. The MRTG page always display the same ports. Is there any way make it auto detecting and displays probably?

Thank you.

Is it possible to have one end configured as l2 while the other end as l3 port-channel? Does this kind of configuration (mix of l2&l3) work?

Many thanx

Comment on Configuring Link Aggregation with EtherChannel by Ernie Gronblom

Which? 1600 Mbps (Fast EtherChannel, full duplex) or 16 Gbps (Gigabit EtherChannel)
1600 Mbps is 1.6 Gbps! Probably 16000 Mbps.

Static ARP, of course!

I knew how to trigger it in the same subnet, but not from another network. Thanks for the information.

GTAP is trully a wonderful programme. Its been a month now since I started and I must say it has not been an easy ride. Even though there is so much stress I know at the end it will be worth while.

I have passed CCNA and starting with CCDA on Monday.

Fabio, any tips that you can give regarding the programme, the TRP’s and just in general how you managed to keep calm till the end of the programme?

Still i am not getting your solution, i read you links but my doubt is i congifured load balancing but when i am taking report utilazation is showing very high for one router and approx null in second router.

router1-i(config)#interface vlan10
router 1#ip address 172.16.1.2 255.255.255.0
router1#glbp 1 ip 172.16.1.1
router1(config-if)#glbp 1 preempt
router1(config-if)#glbp 1 priority 150

router2-i(config)#interface vlan10
router 2#ip address 172.16.1.3 255.255.255.0
router2#glbp 1 ip 172.16.1.1
router2(config-if)#glbp 1 preempt

but still load balancing not happening.

From PC you can check the arp table.
You can check the traffic using SNMP query.
Waht type of loop?

Hi all.

my concern what is the use of Glbp is incoming traffis is high.
i have two router on both configured the glbp but at time only one is working because my incoming traffic is high.is any way to share the incoming traffic on two links?

Comment on Configuring redundancy with GLBP by Dyobbs

Dyobbs — Thu, 19 May 2011 11:29:48 +0000

How do you know in which traffic does the PC goes to? Can you monitor the traffic for each of the links? What happens when there’s a loop? How will you react?
