Cisco Switching/Routing :: WS-6748-GE How To Remove Old Configuration Of Previous Modules
Jan 23, 2011We currently have two 6509's running in VSS, both switches have a WS-6748-GE module in slot 3. I'm in the processing of removing these modules. I will then be replacing them with a different module type, but I need to know how to remove the old configuration of the previous modules.

Cisco Switching/Routing :: High Memory Utilization On Line Card 6748 And 6724?
Apr 15, 2012I am writing with regard to a high memory utilization that we have on a pair of line card WS-X6748-GE-TX and WS-X6724-SFP for a VSS 6500. I am enclosing a little part of the "show tech"of this VSS 6500 where is possible to see the high memory utilization of the line cards 1/1, 1/2, 2/1, and 2/2, in despite of having some ports in state connected. In addition of this, the IOS installed on VSS 6500 is s72033-ipservicesk9_wan-vz.122-33.SXI6.bin for checking if there are some bugs affecting the behaviour of the Switch for this case.

Cisco Switching/Routing :: 2960 / SG 300 Switch - VoIP Setup - Asymmetric Routing Not Working
May 21, 2013I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
Cisco Switching/Routing :: 3750 To Squid Routing Not Working
Nov 23, 2011I am using a cisco 3750 in my network as a gateway, and above it I use a squid machine for caching my internet. My network is like this:
Basically I have two VLANs on my network which are VLAN10 and VLAN100, VLAN10 is the cooperate network of my office. VLAN100 is the management VLAN which i use for the switches. I keep the squid as well the client in VLAN10.
squid (192.168.1.50)---->cisco 3750(192.168.1.123)---->Distribution Switch(cisco 2960)---->client PC (192.168.1.5)
I have done nating on squid and internet is working pretty fine when I use the client gateway as the squid, but when I use the cisco 3750 as my gateway after adding route maps for forwarding the internet traffic coming to the cisco 3750 to squid it disconnects me from internet as well I cannot even reach the switches from the corporate network. These are the only Lines I used for the routing:

Cisco Switching/Routing :: 3750 / PBR Routing Not Working?
Jan 3, 2012My network is like this:
Cisco 3750 (Core Switch)-----> Cisco 2960 (Distribution Switch)-----> Client (PC, Laps, Printers…etc)
Basically I have 3 VLAN’s. Office VLAN (for cooperative usage) which is VLAN 999 which has a defined IP address of 192.168.1.123 and Guest VLAN (for the guests who visits our hotel, most of it are wifi AP’s) VLAN 20 which has an IP address of 10.172.4.1. All these SVI are defined on the core switch.
Is there any way I can introduce a new VLAN lets say VLAN 40 and use PBR to route the packets going to VLAN 40 in the IP range 192.168.1.x to VLAN 999 and 10.172.4.1 to VLAN 20? I have tried this already and it is not working. Here are the configurations I have used.
Access-list 110 permit ip 10.172.4.0 0.0.0.255 any
access-list 120 permit ip 192.168.1.0 0.0.0.255 any
route-map INT_RVLAN permit 10
match ip address 120 110
set ip next-hop 192.168.1.123 10.172.4.1
interface VLAN 40
ip policy route-map INT_RVLAN
Where have I gone wrong?

Cisco Switching/Routing :: 6500 ACL Using QoS Not Working
Jul 16, 2012We are setup like a hotel style workers camp. We have wings full of rooms and residents with 3750 stacks in them. Those switches connect back to our core 6500's. The network is mostly all Layer 3, interfaces are routed with IPs.
When it was built before my time they included an ACL for each wing so that residents couldn't access internal devices (IE SSH to 6500) but I've come to notice it's not working.
I see hits on the ACL for accepts but nothing is hitting the deny rule at the top.Here is the configuration below:
mls qos aggregate-policer INTERNET1 24000000 80000 80000 conform-action transmit exceed-action drop

May 1, 2013I have a 3945 router with two interfaces connected to my firewall, one to the management interface and another to my dmz. I'm running eigrp between all my network devices. The problem I'm running into is when I try to ssh to the management interface of the 3945 the traffice hits the firewall, then goes right to the management interface as it should, but the return traffic is trying to use the dmz interface since that is how the router knows to get back to my computers network. I created 2 route-maps to try and address this issue. [code] I've applied the MANAGE_IN route-map to all interfaces that might have inbound traffic destined for the management network and applied the MANAGE_OUT route-map to the management interface. The MANAGE_IN policy appears to be functioning correctly, the MANAGE_OUT doesn't appear to be functioning correctly. When I look at traffic from my host going to the management interface I see it still trying to return through the dmz interface.

Cisco Switching/Routing :: GVRP Not Working On SG300-28
Feb 28, 2012I have three Cisco SG300-28 switches. I setup a test lab environment with a core (server) switch in Layer 3 mode and the rest are (clients) in Layer 2 mode. As I understand, these switches doesn't support VTP, only GVRP. And GVRP works the same with VTP. Whenever you create VLANs on the core or main switch, other switches will learn from the core switch and no VLAN creation for the client switches will be made. (Hope I got it right. I guess GVRP is more complicated than VTP). I want to use GVRP to create VLANs on the main switch so that I won't be doing it all over on the other switches. The following is my (so far) configuration through CLI only:I haven't use the web GUI. My SW version is 1.1.2.0.
1. I already enabled the GVRP globally.
2. I configured GE 12 & GE 24 as TRUNK ports for the core switch that connects both switches, I also configured GE 12 ports for both the client switches. All other ports are in ACCESS mode. (I am connected to GE 2 port)
3. I enabled GVRP on the TRUNK ports only for all switches.
4. I allowed all vlans on the TRUNK ports. (#switchport trunk allowed vlan add all)
5. All TRUNK ports registration mode is NORMAL and dynamic vlan creation is enabled on all trunk and access ports.
6. I created 3 VLANs without configuring its IP Addresses:
-vlan 2 = MGT
-vlan 3 = IT
-vlan 4 = MKTG
I don't know if I missed something on the configuration or the connection.
1. Is it necessary to enable all switches to layer 3 mode? Or depends on the network setup? Does this affect the GVRP?
2. Does switching ports to TRUNK mode means they are already 802.1q ports by default? Because I can't configure TRUNK ports to 802.1q (#switchport encapsulation dot1q) config like other switches. [code]
Cisco Switching/Routing :: WS-C3750X-48T-S - No Shutdown / Not Working
Jan 5, 2013I'm experiencing strange issue with my WS-C3750X-48T-S.

This switch is situated on a remote site and on the 6th of January it was rebooted.
I still do not know the cause, but it might be power outage or smth. We are still checking. After the reboot I've noticed that one port on this cisco switch is in 'notconnect' state, while I'm pretty sure it should be 'connected'.
I've tried to shutdown the port adminstratevly and do the 'no shutdown' but this port remained in 'disable' state.

Cisco Switching/Routing :: 3750G ACLs Not Working
Sep 17, 2012I am trying to create an ACL that walls off a VLAN and only allows it to the internet. This is on a 3750G, currently the 3750G I am attempting this on is in a stack. I have another 3750G that is a standalone.
The first way I attempted this was to create two access-lists: access-list 101 permit tcp 10.249.1.0 0.0.0.255 any eq 80 access-list 102 permit tcp any 10.249.1.0 0.0.0.255 established
Let's call the 10.249.1.0 VLAN 2. I applied this to the VLAN2 interface, 101 out, 102 in. It didn't work. If I place a deny statement with nothing else, that works.
The second attempt was this: access-list 101 deny ip 10.249.1.0 0.0.0.255 any access-list 101 permit ip any any
I applied this to a VLAN I wanted to block VLAN2's traffic from reaching, let's call that one VLAN 3.
This lets all traffic from any VLAN (including the one I'm trying to block). If I remove the "permit ip any any", then all VLANs are denied. Which I understand is correct due to the implied deny all. What I don't understand is why it isn't applying the ACL to the specific VLAN.

Cisco Switching/Routing :: Policy Map On 3550 Not Working?
Sep 27, 2012We have a metro Ethernet service, basically our WAN connection, that we use to connect 4 sites. This MOE service has a CIR of 200 Mbps, connected to a port on a 3550-12T running Version 12.1(22)EA5 at 1000 Mbps. We are exceeding our CIR at times during the day for short bursts which is causing the MOE switch to drop packets, which I suspect I am seeing manifest itself in some choppy VoIP conversations and dropped ICMP packets from our network monitoring software. I implemented policy maps to apply an outbound service policy to the interface connected to the MOE service, but I am not seeing any matches to the access lists or the service policy. I’m not sure if I am missing something or perhaps the IOS is not capable?
Below is the config for the service policy and some command output. Notice that there are hits on a statndard access list that is used for other purposes, but the extended access lists used for the class maps have no matches.
