Cisco Infrastructure :: 1921 / Implement Dynamic QoS Between Two Sites Across Low Speed WAN Link (512k)?
Jan 15, 2013I have a trouble to implement dynamic QoS between two sites (Site A, and site B) across low speed WAN link (512k). On each site I have Cisco 1921 router. Most important app is Oracle. Because of slow speed WAN links, I want to avoid exact bandwith reservation for Oracle. I only reserve 5% bandwith for network control(icmp, ssh, telnet...) and want configure next Qos scenario:
1. If Oracle traffic exist on a network, it must have 70% of link speed guaranteed, all other apps (e.g mail, file share, ftp) use rest of the bandwith.
2. If there isn't Oracle traffic on a network, all other apps can use all available bandwith.
Issue descrtption:I used all Cisco guides, but when I implemented this on production it simply didn't work. There is no any significant improvement after implementing this (when I start network file sharing accross wan link, Oracle becomes etremly slow.).Here is configuration wich I trying to implement:
ACL-s and class-maps used to mark traffic:
access-list 119 remark ###QoS-MGMT###
access-list 119 permit tcp any any eq 22
access-list 119 permit tcp any any eq telnet
access-list 119 permit icmp any any
access-list 120 remark ###QoS-DB_ORA###

Cisco Switches :: SGE2010 Switches - Best Way To Implement Redundancy
Oct 31, 2012I currently have two SGE2010's with a 4-port LAG configured between them. I'm looking to add another two SGE2010's and I want to add redundancy at the same time. The switches are currently in standalone mode. I don't have fiber connectors and was planning on just using copper for the uplinks.
My questions are:
- Is it possible to use stack mode in conjunction with 4-port LAG groups to create redundant 4-port links between all of the switches? The documentation says that ports 24&48 are reserved for stacking - does that mean I can't specify a LAG instead?
- If 4-port LAGs aren't possible, does that mean that these switches max out at 1Gpbs uplinks if you use stack mode?

Oct 4, 2005I used to be able to set an uplink port with the interface command "port network" so that it would not learn all the mac addresses that are being flooded down to the switch. It does not seem to be there on the 2950's or 35XX switches.
Where did it go and what is replacing it? Interface is a Trunk port as well.

Oct 13, 2011We recently purchased a SF 300-48P to replace a Layer 3 3Com switch that died. I've sucessfully put the switch into Layer 3 mode and assigned ip addresses to each of the VLANs but I cannot figure out how to implement routes for those. Here's some info on our network and what the previous switch had. [code]
Not sure if this can be translated into the Cisco or not.. If i try to create an IP route like these i get errors that the Gateway can be a route.

Feb 4, 2013I'm having some serious sound problem with some 2950 Cisco switches that I have in my CCNA lab these switches sound like a jet I've gone in and made sure the fans are clean and I even replaced one they still are too loud. So I have a few options I can run them without a fan which I really don't want to do but I want to look at two other options. The first option would be to put a heat sink on the chip that's producing heat I also thought about cutting a whole in the top and mounting a 120mm fan.

May 14, 2012have setup a small lab as per CBTNuggets. Everything was going well until I introduced a second switch to create a trunk. Now I cannot ping between my two switches. Both show operational mode as down:
SWITCH1#show interfaces f0/12 switchport
Name: Fa0/12
Switchport: Enabled
Administrative Mode: trunk
Operational Mode: down
Administrative Trunking Encapsulation: dot1q
[code]....
I have tried to allow all vlans or vlan 1 specifically and the output of the above doesn't seem to change. I am wondering if there is something in the config-register that is preventing trunking, but I don't really know enough yet!
The output of my second switch is identical to this one, the only difference is that I have it configured as a vtp client.
Cisco Switching/Routing :: Private Vlans Across 2960 / 2950 Switches?
Nov 12, 2012I am aware that private-vlans are not supported on edge switches like 2960 series - so my question is would it be possibel to ceate private vlans on say just the core switch which would be a 3570 or 4506 that supports private vlans and then just trunk these to the edge like normal vlans?what I need to achive is to have edge port not able to communicate to each other even across switches - which cannot be done using 'protected' port so need the private vlan feature?

(snmpv2 or v3, OID .1.3.6.1.2.1.31.1.1.1.6)I believe pretty much any Cisco Catalyst above a 2950 do, however don't believe any of the SG series do. I realize I could pick up a 2960G for $1500-2k and be good to go, but I forsee a larger switch purchase in the future, but still could use a switch in the meantime that was able to allow accurate monitoring of closet uplink bandwidth?

Feb 18, 2011I have a number of class-'c's as a hand-off from my data center fiber to my 2960, which then sprawls the racks with about many 2950 switches, mostly 20 machines per switch. To allow machines on one 2950 to push data to another 2950 without routing back to my ISP's router(which costs money for bandwidth) isn't is possible to trunk one port on each 2950 to another 2950 and adding a addititional vlan8 to them. Then data jumps from 2950 to 2950 without going back to the 2960 or mainly not going back to my ISP's router. Is this the correct way to accoplish this with extra vlan and trunking the 2950's to each other or am I looking at this all wrong?

Aug 27, 2012I have more than 20 Cisco switches in my office which is basically a soap manufacturing factory. The switches include Cisco 2950, 2960, 3560, 3750 etc. We have routers also which include 2821, 2951 etc. We also have Cisco WLC 2125 and LAP 1262 series. Sometimes all these devices management comes very tough to us.
We need to log on to different devices for troubleshooting/network management which sometimes becomes very tough to us. So I wonder if there any Cisco applications or tools by which we can centrally manage all these devices.
Cisco Switching/Routing :: 2950 - Private VLAN Across Trunk To Older Model Switches
Mar 7, 2012I am looking into the possibility of using private vlan's for some dmz implementations however I do have what may be some very rudimentary questions. It seems straightforward how to configure the primary/secondary vlan configuration as well as associating them. However in my case I would be looking to configure the PVLAN on a 6500-vss platform acting as the router while all of the hosts which I would desire to have in the isolated vlan would be spread out across a number of older Cisco switches which only support "protected port" setup or Procurve switches all of which I do not have budget to replace with something newer. So in my scenario I would have a 6500 connected by trunk to multiple switches which only support a protected port setup such as a Procurve (top of rack) or a Cisco 2950. As the Procurve or 2950 would not support Private VLAN setup, do I then just configure the secondary vlan to be allowed across the trunk from the 6500, configure that vlan on the Procurve or 2950 (as vtp will not foward the info for the secondary vlan) and assign that vlan to the host port as well as setting it as a protected port and this will communicate just fine across the trunk to the router as well as stopping the protected port in top of rack switch 1 from being able to communicate to a protected port in top of rack 2,3,etc? If the above scenario is what needs to be done, do I just use a regular trunk or do I have to use a PVLAN trunk?

Mar 30, 2012I understood that service provider will use hardware Alcatel 6850 on the distribution/core and Zyxel 2108G on customer access level.query is that service provider says it's not VPLS which should work most probably through MPLS network of ISP.ISP noted that it would be direct 802.1q VLAN between two sites without any Layer3 on ISP side.
How to:
- understand what kind of connection this will be?
- is this connection is fine for customer?
- identify if this kind of connection will be fine for converge network (voice+data) ?
- what should I ask to ISP to clarify details?

Connecting Layer2 Switch To ADSL Router
Nov 20, 2011A Layer 2 switch with IP Address 192.168.1.4 (Vlan0), subnet 255.255.255.0 is physically connected to ADSL Router with IP address 192.168.1.1 (which is also the gateway address for the switch). The problem I have is that all the devices connected to the switch can intercommunicate but are unable to communicate with devices connected to the Router. I guess this may be something to do with how the Vlan is configured on ADSL router?
