Cisco Switching/Routing :: 4500 VLAN Administratively Down

Dec 10, 2012

read the posts regarding vlans that are administratively down, they suggested that they are down if no ports are assigned to them, however I do have a switchport assigned, and the interface is still down. This is on the vtp server and on the clients. The vlan is not listed when issuing show vlan brief. Other vlans configured in a similar way do show and their interfaces are up. These are two Catalyst 4948-10G.Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500-IPBASEK9-M), Version 12.2(53)SG5, RELEASE SOFTWARE (fc1).

Cisco Switching/Routing :: 4500 - Enabling DHCP Snooping On 1 VLan?

Nov 24, 2011

I got some problem with  enabling dhcp snooping on 4500 (cat4500e-lanbasek9-mz.122-54.SG.bin) the topology is as below: dhcp snooping enabled only on CORE (with interface trusted to dhcp server)the problem is that I put these 2 commands

ip dhcp snooping
ip dhcp snooping vlan 1
 
but it is not enabled on any vlan
  
SW-CORE#sh ip dhcp snooping
Switch DHCP snooping is enabled
DHCP snooping is configured on following VLANs:
none
DHCP snooping is operational on following VLANs:

[Code]...
 
On B1 if I turn it on there is a "1" in the section " DHCP snooping is configured on following VLANs:" but on core no.As you can see I did put the trusted on the interface in the direction to the dhcp.First I thought it can be a problem with option 82, I've read a lot about the issues with that, but the problem would be explicable if the client did receive IP address, but it does.

Cisco Switches :: Used Two SF-300 Switch And Create 4 VLans And Inter-VLan Routing

Apr 8, 2013

I used two sf-300 switch and create 4 vlans and intervlan routing is working fine.
 
Port 1 - 10 -------------> Vlan 1
Port 2 -20----------------> Vlan 2
Port 3 - 30------------------> Vlan 3
Port 4 - 40--------------------> Vlan 4
 
giga1  -----------------> connected to router (This router used for intervlan routing).
 
SF-300 Port 1 is connected to Internet Modem.  This modem worked as dhcp server also for vlan 1, my problem is that when vlan 1 is not communicate to vlan2,3,4 and 2,3,4 are not communicating. 
 
How i can communicate vlan 1 to 2,3,4 vlan. 
 
how i can connect the modem in switch?  Access port or Trunk port ( Presently available in vlan 1 Access port)Any route i need to make? sf-300 or modem or router?

Cisco Switching/Routing :: 3750 - Extending VLAN To Remote Switch That Already Has VLAN ID In Use

Jan 10, 2013

I 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 :: 3750G / VLAN 1 Is The Only VLAN And Its Disabled

Sep 16, 2012

I 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?

Cisco Switching/Routing :: L2tpv3 Vlan-to-vlan Tunnel On 890

Jun 13, 2011

I 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, 2012

We 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
 
Client Interface on the Switch:

interface GigabitEthernet3/0/1switchport access vlan 2switchport mode accessswitchport port-securityswitchport port-security aging time 2switchport port-security violation restrictswitchport port-security aging type inactivitymacro description cisco-desktopspanning-tree portfastspanning-tree bpduguard enable

Cisco Switching/Routing :: Does 4500 Support VSS?

Feb 28, 2012

Does the 4500 support VSS (Virtual Switching System) ? On the official product overview page it says: 1.6 Terabits capacity with Virtual Switching System (hardware-ready)What means Hardware ready ? Does it mean that it supports VSS in the same manner as the 6500 ? The reason I'm asking this question is that I didn't find any info on the Internet about this. We would like to upgrade our network by interconnecting the 2 sites with Layer 2 redundant links (Layer 2 extension), but I'd like to use the both links in a load-balancing manner, which can be a real pain in the *** with STP. The choice is between 4500 and 3750 stackable  core switches. The 6500s are very expensive.

Cisco Switching/Routing :: QoS In L2 Switches 2960 And 4500?

Mar 12, 2013

We have 3 layer LAN architecture, layer 1 of 6500(IP routing), layer 2 of 4500(L2 switch only), layer 3 of 2960(L2 Switch)In a Single (2960 and 4500) Switch Port Avaya IP phone and PC are connected.Now, the requirement is that, Qos need to be configured for Voice traffic and Data traffic should be in default class of service.We plan to use COS value in Switch 4500 and 2960. We made a sample configuration as below 
 
### For 4500 Switch
 class-map match-all VOIP-Access-2MB
  match cos  3  5
class-map match-all VOIP-Uplink-20MB
  match cos  3  5

[code].....
 
check these configurations are correct as per standard and if there is any other method of configuration?What need to be configured in L3 Switch(6500)??In 2960, it doesn't support ingress QoS, what impact it will make when compare to 4500? do users experiance any difference?
