Question is does it support Device Level Ring (DLR) capability. I do not see this specifically mentioned in the Data Sheets but it talks about a
Resilient Ethernet Protocol (REP) and I am wondering if this is the same thing?
In the Dual ring network using the token passing method, we have the primary ring and the secondary one where in the normal situation only the primary ring is carrying the token in one direction and when this ring is down the secondary will start into operation and takes the token and rotate in the inverse direction of the primary to reach its destination. Why the secondary ring doesn't continue in the same direction to the destination?

View 2 Replies View RelatedI am migrating from ACS 4.2 to 5.2. In 4.2 you could assign one user to auth via Internal Database and another user to auth via Radius Token Server. I cannot find how to do this with 5.2. There is a note in the doc that states 'Identity-related attributes are not available as conditions in a service selection policy'. Does this mean that you can only choose one auth method for all users? If it is possible to have multiple methods, how am I able to accomplish this?
View 1 Replies View RelatedI have ACS4 and i am planning to upgrade to ACS5.I would like to have such a rules:I have user1, one ASA device which is VPN concentrator for remote users.ASA have two different tunnel-groups: one which allow for logging via certificate (with mandatory pki authorization thru ACS) with disabled Xauth,and second tunnel-group with allow login thru typical Xauth with authorization thru ACS which users external database (RSA Tokens).So i have one user1 which can login thru VPN using RSA tokencode or certificate.For example: on phone user1 uses certificate, and on PC station the same user1 uses token password.For tunnel-group with pki authorization ASA checks username in ACS and in typical scenario login="CN from certificate" and password="CN from certificate". So we would need "two credentials" for the user - one for pki authorization, and second one external database (RSA token).Is such scenatio possible under ACS 5 ? where one user uses different credentials based on tunnel-group usage ?

View 3 Replies View RelatedI'm planning to use 2 3560X (access switch) on two different locations connected over two 2921 routers in small ring. 3560Xs are directly connected via fiber. Each 3560X is conected to its own 2921, and 2921s are connected together with GRE over IPSec. So they are creating ring.I'm planning to use small area 0 in this scenario. There are less then 200 routes in the network. Will 12.2(55) IP Base on 3560X support this scenario or I will need IP Services image? "OSPF for routed access" is still little vague to me, there are only tipical case study scenarios.
View 22 Replies View RelatedI've looked in many places but cannot see how or if it is possible to configure a phone, in CUCM to have a feature ring instead of the normal ring.In CUCME you go into the ephone x configuration mode, and assign the DN to the phone with the button xfx command. What this gives you is a slightly different ring tone when a call comes through. If I am not mistaken it is the same ringtone they use on the show "24".Is there a way to do this "feature" with CUCM?
View 1 Replies View RelatedMy topology is a physical ring, and I need transfer IPTV signal to all site along the ring.For example:
A (headend)--- B --- C --- D
|______________________|
Note: -----: have spoke-mesh defination
_____: no spoke-mesh defination to prevent loop
So, with MPLS/VPLS I can implement it. With spoke and mesh defination, the traffic can transfer form A to B, C or D as drop-continute action in ring topology (between different VC). Everything is good, FRR can work very fast. But when the topology have a failure link, for example the link between B and C, at that time the traffic will go from A to B then B come back to A and A --- D ---C. This action is so stupid, because it can increase delay, jiiter in network. On the other hand, when the node failure ( B failure), C will loss the IPTV signal, even the link from A--D--C always good.
has anyone here played around with uploading compatible audio files for custom rings and MOH and/or personalized backgrounds for the phones? I was only taught the basics in our CUCM v6.0.1 and am looking to figure out how to get some good music on my phone as well as play around with other "cosmetic" features. The phone I'm testing with is a 7971(color).
View 4 Replies View RelatedI need to setup a layer 2 network consisting of 14 switches interconnected in a ring. Obviously, the design of 14 switches in a ring network is dumb, not here to debate that. Unfortunately, it HAS to be a ring. I've been researching the best way to configure RSTP for this. From everything I've read all I really need to do is configure Primary/Secondary root bridge in the center, and change the Maximum Age field to at least 16 seconds? From what I've read you want a minimum of 3 second buffer + 1 second for each hop due to message age being added by each switch hop?
View 8 Replies View RelatedI am looking for a Best Practices or a few places to pay attention to in the Cisco ESW-520-48P switch I have. My VoIP solution is RingCentral, and while they are Cisco phones, I've been hestitant to setup VLANs etc. the way I am used to. Plus setting up Auto QoS seems different than what I am used to with a 3750 switch.
Right now I've left the Smartports Wizard alone, and none of the ports are configured. There are no VLANs or QoS on the LAN currently.
What I was running into were calls cutting out where one side wouldn't hear the other anymore, but the call would remain connected. However, this has happened in this small 15 person office, when there is only one employee here after hours, talking on the phone. There isn't any heavy network traffic, because I have network monitoring showing me low usage (no streaming music, videos, or anything else).
This switch has a Gb connection to a Linksys SR2024 (the server switch), which is also set at Factory Defaults. I mention that because I recently bypassed the ESW-520-48P, and plugged one phone into that switch and the RingCentral phone worked fine for outside calls.
Is there something besides QoS that I should look at in the ESW-520 switch that might be causing a checkpoint of some sort, or interrupting VoIP traffic that I need to configure or disable?
And are there any Best Practices or scenario guides for this switch? I found the Admin Guide, but it really just explains every option in the GUI for the switch. And it seems all of my CCNA training isn't working with going in and quickly troubleshooting this switch besides knowing that something in it could be hanging it up.
I´ve got a strange problem with the connectivity within a ring topology.There are five switches from the SGE2000 series and one SG200-50.The SG200-50 is the root bridge and RSTP is configured.From the root bridge switch (Switch 5) I can ping Switch 0.But I cannot ping Switch 0 from PC0.
On the other hand I am able to ping all other Switches (1-5) from PC0.In addition to that I can establish a RDP connection from PC0 to Server0.This tells me that there is no general problem with the connection from PC0 to the Switch0.
Right now when I want to configure Switch0 the only way is to connect to Server0 first.But we have to move Server0 and this is why I want to manage Switch0 from PC0 like any other Switch on that network.
I'm looking for a good managed (i.e. a unit with stats and troubleshooting capabilities) fiber-to-copper media converter.

I'm converting between 50nm multi-mode fiber with an SC connector to 1000-bT copper.

The AD database not only authenticate the users but also assigns the group that is used to select IP address pool.Now the requirements require to use token authentication with SafeNet. This authentication uses the same username but the password is composed of the original password + OTP.The problem is that the SafeNet server doesn't return the group membership.I've read about the Identity Store Sequence in ACS 5.x and I think I could use it in the following sequence:! configure an Authentication Sequence using the SafeNet token server (this works with ACS 4.x)I configure an Attribute Retrieval Sequence against the AD database. This would use the username only, no password and would retrieve the group membership.

I'm trying to upgrade some of the netwotk in my workplace.To do this I have istalled a 24port Catalyst 3560X switch.I'm looking to link it to my exsisting network via fibre.
I spoke to a local Cisco supplyer who recomended the above switch and an Allied Telesis Media converter.
I cannot seem to get the Allied Telesis unit to connect to the cisco switch.I have proved the fibre link by connecting 2 AT Media converters over the fibre.Do I have to enable something on the Catalyst switch or is the AT Media converter not compatible with the Catalyst switch?

To do that I would like to be able to sniff the traffic traversing our 7k. However, as the 7k doesn't support remote span we have to span locally. This means that I have to connect a pc to the Nexus and sent the span output to that port. However, our 7K is only equipped with N7K-M108X2-12L modules, which contains X2 10G ports. I found the CVR-X2-SFP10G X2 to SFP+ convertor module, but I wonder whether this supports a 1G copper SFP. If it doesn't it would be wasteful to buy one. On the page concerning the module I only found 10G fiber sfp's which are supported.
