Cisco Switching/Routing :: Cannot Use A Number For VLAN ID Other Than 1 To 4094
Jan 5, 2012If multilayer switch has routing capabilities then why we can go for dedicated router?
Why we cannot use a number for VLAN ID other than 1 to 4094 ?

Cisco Switching/Routing :: 2960 LAN Lite / VLAN Number Max 64?
Jun 6, 2013we have inserted into a network with VTP a Cisco Switch 2960-S, not knowing that had installed IOS LAN lite.Now I discovered that it can handle up to 64 vlan. In the network there are currently configured 62 VLAN: what happens when we exceeded the max number (64) of VLAN for that switch?

Jan 10, 2013I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50
10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
Cisco Switching/Routing :: Route Data From Vlan 10 To Vlan 20 On 2960s?
Mar 31, 2013i need to solves this little problem on 2960S lan BASE but i dont know if it is possible.
Uplink port config for gi 1/0/28 is:
switchport mode trunk
switchport trunk alloved vlan 10,11
but on interface gi 1/0/1 i want to have data from vlan 10 tagged as VLAN 20.
At this time i have solved this issue very primitively
I have set up gi 1/0/2 as int mode acces, acces vlan 20 and i have connected gi 1/0/2 with gi 1/0/3 with eth cable. int gi 1/0/3 is switchpor mode acces, switchport acces vlan 10
Cisco Switching/Routing :: 3750G / VLAN 1 Is The Only VLAN And Its Disabled
Sep 16, 2012I have a 3750G switch in my production network that only has VLAN 1 on it. All ports are in a default state and VLAN 1 is disabled. The switch is passing traffic but shouldn't having the default VLAN shut down cause the ports not to pass traffic? If I start to create VLANs will that cause the switch to stop passing traffic?

Jun 13, 2011I am trying to setup a L2tpv3 VLAN-to-VLAN tunnel.My setup has two Cisco 890 router with Cisco IOS Software version 15.0(1) M4. These routers are connected directly on FastEthernet port 8.
One linux machine is connected on FastEthernet port 0 on each router. The two linux machines are on same vlan. I am trying to establish a vlan-to-vlan tunnel between the routers and send traffic between the linux machines.
I followed the case study 11.4 from [URL] and configured the l2tp-class and pseudowire-class. However, the vlan interface configuration is different on 890 router.
I configured a vlan interface as follows.
(config)#vlan 200
(config)# interface FastEthernet 0
#shutdown
#switchport access vlan 200
(config)# interface vlan 200
I don't see the 'xconnect' command in this context. What's wrong with my configuration?
Cisco Switching/Routing :: Low Bandwidth On 3750 From Vlan To Vlan?
Nov 20, 2012We have a low bandwith (15-20 Mbit/s) to the ASA from our Client vlan. If i connect the Client to the same vlan as the ASA is, the bandwith (90 Mbit/s) is good.
Here are the Layer 3 Design:
Client -> vlan 2 - Switch - vlan 7 -> vlan 1 - ASA 5505 -> ISP
The Layer 2 Design:
Client -> Gig2/0/13 - Switch - Gig4/0/43 -> Eth0/1 ASA5505 -> ISP
IP Address:
Client: 172.16.2.10Vlan2: 172.16.2.1Vlan7: 172.16.7.1ASA: 172.16.7.2
I assuming the switch has a problem with routing ?It is a stacked Switch with following members:
switch 1 provision ws-c3750g-12sswitch 2 provision ws-c3750g-24tsswitch 3 provision ws-c3750g-24tsswitch 4 provision ws-c3750x-48
And we have following error message in the log from the switch:
%PLATFORM_UCAST-4-PREFIX:
One or more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded I first get the idea that the switch is overloaded with router traffic. Thats why i assuming i have to check the sdm templates, but i'm not sure if this resolves the issue.
Here are the relevant config:
ASA Interface on the Switch:
interface GigabitEthernet4/0/43description ASA-inside LANswitchport access vlan 7switchport mode accessspanning-tree portfast

Cisco Switching/Routing :: Max Number Of VLANs On A 6509-E?
Mar 18, 2012We have the need to create a large number of VLANs on one of our networks. We're talking about 60! These will all terminate on a pair of 6509-E switches (building core). We use MSTP as a standard on our network so I'm going to stick with that so that we can dramatically reduce the number of STP instances needed. However, regarding the SVIs (default gateways) is there any reason why creating 60 of these guys would be considerd a big no-no? Or would you expect the 6509s to deal with them like a boss?

Oct 30, 2012We have IP device on the farm switch(cat6500, which is an access layer siwtch), with the gateway on the core switches (Nexus7000), on the core when I do show ip arp, I found the mac.But when I do sh mac add add of that mac there is no port attached to that mac.
Since that particular vlan only resides on the cat 6500 and two cores, so I logged in to the 6500, and when I show mac- in that vlan, I didn’t find that mac addresss. Instead, I found another mac address with last 8bit are the same of that mac.
Is it some kind VIP of the mac? How so, if no port, how can the switch forward the frame? [code]

Cisco Switching / Routing :: Increasing Number Of Overrun In 6509?
Aug 12, 2012I found increasing number of overrun in the tengigabit interface. The hardware is 6509 with sup720-3B and the overrun output is shown in WS-X6716-10GE module. The connected device to WS-X6716-10GE is EMC Islion S200. I think the capability of WS-X6716-10GE can handle EMC NAS device and the load is not so busy. So I have no idea of handling this and the reason why this overrun packet is shown.

View 1 Replies View RelatedCisco Switching/Routing :: C3560 / Number Of Supported Spanning Tree Instances?
Sep 9, 2010I'm having some weird issues with our 3560 that's connected to an MPLS line. The speed of the port plugged into the providers equipment is 100Mb, but we're only allocated 10Mb of bandwidth from them, I tried to police our traffic out of the port using srr-queue bandwidth limit 10, however when I do that I get some really weird bandwidth results.
Using iperf I've run bandwidth tests with srr-queue bandwidth limit enabled and with it disabled, when it's disabled I get the full 10Mb as expected, however once I enable it I'm lucky to get 5Mb, and while the test is running connectivity between sites is almost useless (which is not the case if I disabled bandwidth limit). Is there anything special I should be doing when I have this enabled? I also have priority-queue out enabled with only one dscp marking placed in queue 1, with very little traffic hitting that queue, but regardless of what I do I can't get the expected bandwidth with the bandwidth limit command, even if I place my iperf traffic in that priority queue.
