Cisco Switching/Routing :: 2960S - Multicast Imaging And VLANs

Oct 2, 2012

This is the deal, I used Acronis for imaging workstations.  Obviously when I do that it drags everything down to a halt, as all the ports are being flooded with packets.  So what options do I have to image (as opposed to doing it after hours or try to plug all the computers into one isolated switch? = )
 
VLAN 1 has well everything in it, PXE server, DHCP server and workstationsVoice VLAN 100 is on every trunk or connection a workstation would be attached to.  
  
There is another equipment I'm not illustrating... although a part of me wonders if my topology is correct.
 
In any case, I've read about IGMP Snooping, CGMP, etc-- but I think the 2960S are only capable of IGMP Snooping.
 
And from there I'm a little confused about configuration of IGMP...

Cisco Switching/Routing :: Catalyst 2960S / Multicast Not Working Between Two Data-centers?

Jan 28, 2012

Multicast is not working between our two datacenter, we have catalyst 2960S (two stacked) as the internal lan switch, and catalyst 3560E as the external switch, same configuration for both datacenters.The two sites are connected using metro, the external switch (3560) is doing qinq and encapsulate the data from the internal switch with the metro vlan (611).
 
IGMP snooping is disabled for all switches, although we prefer to enable it for the internal switches.For each datacenter there is a different firewall which also act as the router, we are using fortigate as the firewall.Following is the important configuration section:
 
Port 43 in the internal switch is connected to the external switch (both sites):
 
interface GigabitEthernet1/0/43 
switchport mode trunk
 load-interval 30 
 
Port 3 in the external switch connected to the internal switch (both sites):
 
interface GigabitEthernet0/3 
switchport access vlan 611
 switchport mode dot1q-tunnel 
no cdp enable
 no cdp tlv server-location
 no cdp tlv app
 
 Port 8 on the external switch connected to the metro link (both sites) vlan 350 is the internet and 611 is the metro:
 
interface GigabitEthernet0/8
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 350,611
 switchport mode trunk  

vlan 611 on external switch:
 
interface Vlan611 
ip address 192.168.168.2 255.255.255.0
 no ip route-cache 
no ip mroute-cache

Cisco Switching/Routing :: Multicast Filtering Between VLANS (217 / 64 / 80)

Mar 18, 2013

I have the need to filter multicast between vlans as described below. PIM Sparse-Mode is being utilized for this multicast network and changing any Vlan to PIM Dense mode is not an option.
 
- Vlan 217 and Vlan 4 should not be communicating on mcast with any other vlan, including eachother (each vlan isolated).

-Vlan 64 and Vlan 80 are able to communicate witch each other on mcast but not with any other vlans (isolated vlan group).

-All other vlans can communicate mcast freely.
 
What I've created thus far is below. It does not appear to be the most elegant solution and would be difficult for the administrators to adjust as new requirements come along. Yes, I will be adding the appropriate link-local multicast addresses so as to not break routing and other dependent technologies.

ip access-list ext ANY_CONN
permit ip any any
ip access-list ext MCAST_INTRA_217
permit ip 224.0.0.0 15.255.255.255 133.106.197.32 255.255.224.0
permit ip 133.106.197.32 255.255.224.0 224.0.0.0 15.255.255.255
ip access-list ext MCAST_ISOLATE

Cisco Switching/Routing :: Configure VLANs On SF 300 To Work With 2960S

Sep 21, 2011

make a couple of SF300 switches to work properly with a C2960S-48TS-L that acts as core switch/basic router. I can't seem to figure out how to assign VLANs correctly in trunk and access mode on the SF300. The 2960S are a no brainer with IOS commands but the webgui in the SF300 is a pain.
 
I've configured the 2960S with 3 VLANs and I would like to have the SF300 switches connect to the C2960S-48TS-L through VLAN trunk and then configure the ports on the SF300 switches to belong to the assigned VLANs of my choosing. I would also like to have all the SF300 switches management interface in VLAN 50.
 
I've partially described the enviroment below.
 
VLANs
Data                  VLAN 10:    192.168.10.0
Management      VLAN 50:    10.20.30.0
Voice                 VLAN 100:  10.10.10.0

Cisco Switching/Routing :: 2911 / 2960S - Multiple VLANs With Different Internet Access

Feb 17, 2013

We need to give differentiated internet access to three VLANs. Each one of this VLANs is used for totally different purposes, so traffic between the VLANs is not allowed. Each VLAN has its own internet access provided for the data center using one fast ethernet connection.

We're thinking about using cisco 2911 for Internet access, VPN and firewall. I suppose that best option for VLANs is using Catalyst 2960S or a swithing module for the 2911, but these two options are too expensive for us. We're thinking about using swtiches from the SB series (maybe a SG-200).

We're totaly newbies to VLANs so we have many doubts. This are our questions:

1) The 2911 has three on board ethernet interfaces; we have three VLANs and three internet connections, so we need to use HWICs to get three more ethernet ports. That's right?
2) We need three HWICs or there is some kind of HWIC with more that one ethernet interface?
3) The routing solution is to assign static routes in the 2911 for each interface connected to a VLAN through a 2911's interface connected to internet?
4) Simply connecting three different router interfaces with three different switch ports, each one of them assigned to one of the three different VLAN, are we going to get internet access for all devices in those VLANs? or do we need to configure something else like trunking, VSIs...?
5) Can we achieve our goals using the SG-200 switch?
6) We have the chance to use older routers, is this possible? We're specially interested in knowing if a 1841 or a 2801 router could be used for this setup.
7) This is not a production environment so we can use refurbished equipment.

Cisco Switches :: SG 300-10 Multicast Routing On VLans 10 / 20 And 30

Apr 9, 2013

I am IT teacher at a middle school in Nuremberg, Germany. We have in our school 5 VLANs, 4 Switchtes, 1 L3 switch and 1 router.
 
2 months ago the old L3 switch (Catalyst 3550-12T) is broken. In the short term I've borrowed a Catalyst 3750G-24, so that the network continues to function. Now a SG 300-10 switch was purchased. This should be configured the same as the 3550-12T or 3750-24G.The network looks like this (there are much more PCS than in this image):
 
VLAN ID
VLAN Interface
DHCP
DHCP-pool
[Code]....
 
The DHCP server in VLAN 30 is also a FOG server. The Fog server images all PCs in school. PCs in VLAN 10, 20 and 30 boot from PXE. The MS Server in VLAN 10 has been configured by the DHCP options 66 and 67.
 
The Catalyst 3750G-24 routes the multicast, but the SG 300-10 I do not have the option of using the commands ip multicast-routing distributedip pim sparse-dense-modeto work and must configure igmp. I'm having problems with the igmp-configuration on the SG 300-10. Therefore, I have uploaded the configuration of the 3750G-24 and the configuration of the SG 300-10 (without ACL).

Cisco WAN :: Multicast Routing Between Vrf (Cat 3750) - Multicast Vpn Extranet?

Cisco Switching/Routing :: Why Does Routing Work Without Declaring Vlan10 On 2960s-24td-l

Oct 28, 2012

I have recently split the voice vlan (10) from the data network (1), and am wondering why my catalysts and router do not require an interface Vlan10 statement.  In the past I used OpenBSD boxes to do the routing, and I first needed to configure vlan 10 on the interface before I could get inter-vlan communication to work.  With these Cisco devices it works, and I am wondering if it is because of VTP, for the fact that the ports maybe just pass all traffic, or is there some other explanation?  Below is the setup, and firmware is up-to-date on all of the devices.
 
When I plug a phone into the POE SGE, the phone turns on, obtains an address on the proper subnet, and conversations are clear (whereas without the ip nat inside on the new subnet the calls had a lot of static).  Possibly the reason that it works is because the phones properly create the tcp/ip packet, and it hops over the trunks and creates the states so that traffic routes back properly.  I will install wireshark to see exactly what is going on, but is there a simple explanation that I am overlooking?

Cisco Switching/Routing :: 2821 Multicast Routing Relay Basic

Mar 12, 2013

I  start configuring Cisco 2821 router for multicast . First short  description and attached sheme explanation. Let we say  I have small  network with 100 users. One router and Cisco switch 3560. Two VLAN’s,  one for data another for multicast. Data from internet works fine but  now I want to connect multicast servers (or source of more multicast  streams) from another subnet. Router have three interfaces.I expect there should be no problems with multicast configuration, but unfortunately it is not like I expect. What I did ?

First step:  enable multicast routing

Second step: on both interfaces (Fe 0/1 and Fe 0/2)  - ip pim sparse-mode

Third step: configure switch that users are connected to access port in VLAN 222 (temporary to see if multicast work)
 
When  I start VLC on computer nothing happend. If I try to connect computer  on same subnet where is source of multicast streams it works fine.What  I am doing wrong ? Is there anything about routing ? All subnets are  directly connected. RP is not needed if I have one router or ?

Cisco Switching/Routing :: 6509 - Multicast Routing Preference

Nov 14, 2012

I have a problem on my catalyst 6509 on which I would like to do the following things :
 
I have some Vlans in which multicast is enabled.
In tose Vlan theres is a router which is default router for equipements.
 
I had enabled multicast routing because some Vlan needs to exchange multicast informations, but I wolud like to make difference between Multicast traffic. For example I have 5 vlans:
 
Vlan 1 and 2 need to exchange Multicast informations but the don't need multicast information from Vlan 3 and 4
Vlan 3 and 5 need to exchange Multicast informations but the don't need multicast information from Vlan 1 and 2
Vlan 5 is independant Vlan but doesn't need to have multicast information from all others vlan.
 
Last problem, equipement on differents vlan can use the same Mulkticast group address. In this case, Multicast routing is not working between Vlan 1 to Vlan 2 and Vlan 3 to Vlan 4.

Cisco Switching/Routing :: 4506 / 6506 - Multicast Routing

Mar 8, 2013

I am configuring multicast in a environment where I have a 4506 at each site (4 total) and a 6506 as the core. Each 4506 is connected via layer 3 to the 6506. I have a mix of 3560s, 3548s, and 2960s connected to the 4506s and the 6506 via layer 2 trunk
 
I have multiple multicast sources and hosts communicating at a time (multiple cameras sending video / multiple computers receiving video).  So this is not a scenario where there is 1 sender and many receivers.  This would be many senders (~50) and some receivers (~10)
 
Sample Diagram:
 
->3560
|
6506 --> 4506 --> 3548
|   |
|    --> 2960
|
4506 --> 2960
|
-->3548
 
I configured ip multicast-routing on each of the 4506s and on the 6506. IGMP snooping is on by default on the 3560 and 2960 switches. CGMP is on by default on the 3548 switches.
 
I set up PIM sparse-dense mode and IGMP version 3 on each of the layer 3 interfaces for the 4506s and 6506 where they connect and on each VLAN that is sending or receiving multicast. Multicast is working throughout the network, however I am looking to verify the configuration as I scale this out to more clients on the network. 
 
#1 - Is it correct to us sparse-dense mode in this configuration?
 
#2 - Do I need to configure a rendezvous points using AUTO-RP? (ip pim send-rp-announce INTERFACE scope TTL). Not sure here if I need to designate this and what to choose.  Right now I do not have this and it is working, but documentation seems to infer that I need to designate this.
 
#3 - Is there any other configuration settings I should be considering?  I hard to find real world configurations of multicast as examples or people that know multicast routing well.

The switches are Cisco 2960S with code image "C2960S Software (C2960S-UNIVERSALK9-M), Version 12.2(55)SE3". Should I use autoQoS feature or manually configure them?. How should I treat uplinks between access switchs and core/distribution? I have a lot of doubts regarding queueing, because all the info I had read its for another model/image.

Cisco Switching/Routing :: NTP Multicast On 3750?

Dec 10, 2012

I have a subnet with a GPS clock on it that connects into a Cisco 3750. The 3750 has another subnet hanging off of it that connects into a firewall then to a server. I need the server to get time from the GPS clock. Any way to pass the NTP through the 3750?  The 3750 has the 3750-IPBase code running on it so the multicast support is limited. I am under regulatory restrictions that only allow traffic to flow from the higher security level (were the time server is) to lower security level (were the server is). This prevents me from having the server go to the clock for updates.
