Cisco Switching/Routing :: 3750 Stack And Route-Maps?

Feb 6, 2013

I have a Cisco 3750 stack with 5 members.
 
Switch Ports Model              SW Version            SW Image
------ ----- -----              ----------            ----------
     1 24    WS-C3750G-24T      12.2(55)SE6           C3750-IPSERVICESK9-M
     2 24    WS-C3750G-24T      12.2(55)SE6           C3750-IPSERVICESK9-M
*    3 24    WS-C3750G-24T      12.2(55)SE6           C3750-IPSERVICESK9-M
     4 52    WS-C3750G-48TS     12.2(55)SE6           C3750-IPSERVICESK9-M
     5 52    WS-C3750G-48TS     12.2(55)SE6           C3750-IPSERVICESK9-M
 
I have recently set the sdm prefer template to routing to allow route-maps and rebooted the stack:
 
3750GCORE#show sdm preferThe current template is "desktop routing" template.The selected template optimizes the resources inthe switch to support this level of features for8 routed interfaces and 1024 VLANs.
  number of unicast mac addresses:                  3K  number of IPv4 IGMP groups + multicast routes:    1K  number of IPv4 unicast routes:                    11K    number of directly-connected IPv4 hosts:        3K    number of indirect IPv4 routes:                 8K  number of IPv4 policy based routing aces:         0.5K  number of IPv4/MAC qos aces:                      0.5K  number of IPv4/MAC security aces:                 1K
 
I still cannot apply a route map to a vlan interface however:
 
I have preconfigured the route map as per below to take traffic from one particular client and pass it to the inside interface of our ASA firewall:(yes i know 192.9.0.0 is a public network, its an inherited problem that is in process of being remedied!)
 
ip access-list extended TEST
permit ip host 192.9.216.234 any
permit icmp host 192.9.216.234 any
permit tcp host 192.9.216.234 any
route-map TEST_MAP permit 9
match ip address TEST
set ip default next-hop 192.9.201.10
 
When i do the following I get this error from debug:
 
3750GCORE#config t
Enter configuration commands, one per line.  End with CNTL/Z.
3750GCORE(config)#int vlan 216
3750GCORE(config-if)#ip policy route-map TEST_MAP

007804: Feb  8 03:16:55: %PLATFORM_PBR-3-UNSUPPORTED_RMAP: Route-map TEST_MAP not supported for Policy-Based Routing
  
when I show the running config, the route-map is not there.3750GCORE#show running-config int vlan 216Building configuration...Current configuration : 205 bytes!interface Vlan216
 
no ip redirectsip directed-broadcast 101end
 
why TEST_MAP is not supported?

Cisco Switching/Routing :: Route Maps On A 3750 Switch

Feb 16, 2012

I have a 3750 switch and I am trying to configure PBR (route-maps) in it.But when I try to apply the policy to a vlan interface the policy does not show in the interface.So I can not use PBR to choose my default gateway!Question: Does PBR work in a 3750 switch? Can PBR be configured in a vlan interface? There is any problem with the IOS that I do not know?

Cisco WAN :: Route-Maps On L3 3750 Switches?

Dec 6, 2012

I have the following set up, at one of our sites:What I would like to do is take non 10.x.x.x web traffic, and pipe it through the ISP2 link, and keep all other 10.x.x.x traffic over the main ISP1 link.  I would like to set this up on the L3 3750's that we have.  Here is my configuration for the 3750's (IP's have been changed for security):
 
track 222 ip sla 222 reachability
track 223 ip sla 223 reachability 
ip access-list extended INTERNETTRAFFIC
permit tcp 10.1.1.0 0.0.1.255 any eq www       - Internet LAN subnet
permit tcp any 10.1.1.0 0.0.1.255 eq www
permit tcp any eq www 10.1.1.0 0.0.1.255

[code]....
 
I'm applying the policy route-map to the VLAN interface, but do not see any traffic, once I apply the interface.  I'm not that experienced, with route-maps?

Cisco Switching/Routing :: Adding 3750 To Stack?

Dec 6, 2011

I have two  3750s stacked and one 3750 standalone all in one data closet. The both have the same versions. I want to combine them to make one stack. How do I force the standalone to be the master? sw 1 priority XX(Higher then the existing stack)? Both the stack and the standalone have management addresses. Would it be ok to delete the stack ip address? That way, the standalone(master's address will be the only management address)?How should I connect the standalone 3750 to the stack? At present, the 3750 stack is connected via a cascade cable going from the stack 1 port of the top switch to the stack 2 port of the bottom switch.

Cisco Switching/Routing :: 3750 Stack Port

May 19, 2013

I have a stack of 4 3750 Switches.
 
1. WS-C3750G-12S
2. WS-C3750G-12S
3. WS-C3750X-48P
4. WS-C3750X-48P
 
The stack cable connected to Switch 1 Port 1 and Switch 4 Port 2 will not come back online. The logs show that there was a Stack line change. I have replaced the 1 meter Stack cable from Switch 1 to Switch 4 three times and it still does not come back online. This is the part that is interesting.. I have disconnected Port 1 Switch 4 and connected it to Port 2 Switch 4 and then Switch 4 came back online. This made me think Port 2 on Switch 4 was working correctly. Then I disconnected Port 2 Switch 1 and connected it to Port 1 Switch 1 and then Switch 1 came back online.

Cisco Switching/Routing :: Etherchannel Does Not Go Up / Up From 3750 Stack To 6k5 Vss

May 19, 2012

We have two 6k5 configured as vss and it is working fine. For each floor we have a 3750 stack. In each 3750 stack we have 4 switches. From the first 3750 we have a fiber link to the first 6k5 and from the fourth switch we have another fiber link to the other 6k5 switch, for each floor/3750 stack, both configured as etherchannel. We installled each 3750 stack/floor in different maintenance windows; in all these installations we have problems configuring the etherchannel. After we configure the etherchannel on 3750 stack and in the vss, the etherchannel does not go up/up. We see the etherchannel up/down; after a lot off work, try and error, configuring shut/ no shut, adding and excluding links from the etherchannel; in any aleatory moment the etherchannel goes up/up and works fine. Is there any bug related with these IOS versions, or is there any right procedure to configure etherchannel from vss to 3750 stack?

Cisco Switching/Routing :: 3750 Stack And Trunking

Mar 5, 2012

I currently have 5 3750s connected via Stackwise. This stack is connected back to my core (6509s) via fiber (1Gig to Core1 & 1Gig to Core2). I want to move the 5th 3750 to another closet due to an addition of a new patch panel. Due to max length of 10 ft. for stackwise, my plan is to connect this 5th switch back to the stack using trunked fiber ports, with them being an etherchannel (2Gig). Also plan to use single fiber port form 2 different switches in the stack to provide some redundancy for the 5th switch. Should I be alert of any issues with this connection design? Do I need to properly remove the 5th switch from the stack using, no sw 5 provison sw-model or can I just disconnect stackwise and connect back with fiber?

Cisco Switching/Routing :: Adding A New 3750 To Stack

May 29, 2012

I had 2 3750 stacked and one of them decided to die (power supply) cisco replaced it and now i want to re-add that switch to stack. I have already upgraded my replacement switch to the same IOS version.I was reading that i can do it without powering down operational 3750 so the action plan so far is:
 
-power down NEW member
-connect stacking cable
-power up
 
as you can see my switch 2 is now a master and it still holds config of all Gi ports for switch 1. If i connect my NEW switch without any config (vlan.dat and startup-config) will my existing switch 2 copy all ports config to new switch ?

Cisco Switching/Routing :: 3750 Stack Crash

Oct 22, 2012

We had an "Event" on our process network at the mill yesterday.  I connected a new WS-C3560V2-48TS-S to our network and we lost communications with all of the other switches.
 
The core is a stack of 3 WS-C3750 switches, one is a -24TS-1U and the other two are -12S-S.  These connect to 10 WS-C3560G-24TS and 5 Rockwell Stratix 8000 (IE3000) over fiber.  I am planning on replaceing two 24 port switches with the new 48 port.  I had the switch configured and running at my work bench.  It was connected to the network with one sfp module and ran all weekend with no issues.  Yesterday afternoon I took it to the network cabinet and installed it.  I powered it up and connected two sfp modules to the fiber patch panel and made the connection at the core stack. 
 
Everything looked OK.  I had communication link lights working on everything.  Within minutes, we lost communication with every switch connected to the core stack.  I shut down the new 48 port switch and the network slowly came back up.
 
The new 48 port is configured with Flex Links for the fiber redundancy protocol and was connected to each of the 3750G-12S-S stack members.
 
I though it might have been a power issue but the stack is UPS protected and shows it has been up for over 10 weeks.  I'm not even sure "Crash" is the best decription for what happened.  The new switch has a high enough IP address that it would not take over as a IGMP Querier.

Cisco Switching/Routing :: Stack Behaviour Of 3750 Switch

Nov 17, 2012

I configured 3750 A  switch with vlan 20 and its IP address 192.168.20.41Its default gateway was 192.168.20.3Then i configured 3750 B  switch with same default gateway and vlan 20 IP   192.168.20.43My question is now when we stack it becomes single switch and now vlan 20 ip address is 192.168.20.43 thats only IP i can see.So how does stack switch choose vlan 20 IP?Does it choose highest IP address between two switches if they have same vlan 20 as in my case?Also when i go to switch 3750 b by session command and do sh ip route  it does not show ip default gateway .Also it shows vlan 20 as admin down .

Cisco Switching/Routing :: Changes In TP If Replace 3750 Stack With 3750GS

I am replacing our 2 3750s which are in a stack and are running in VTP server mode for the domain with 2 new 3750Gs.  There are 4 trunks to other switches which bare in client mode and 2 trunks to 2 ASAs which are in active/standby mode (one in each switch).  Anyway what will happen to the VTP clients when I replace the stack as the revision number will be 1 on the server?  The clients will ignore any VTP updates from the server ?

Cisco Switching/Routing :: 3750 - Running 7 To 9 Switches In One Stack

Aug 6, 2012

Looking for feedback from other organizations that have large 3750 stacks.  I've got one stack of (8) 3750's composed of (6) 3750G's and (2) plain 3750's.  This particular stack is usually unresponsive to SNMP queries and often fails to write config when we make changes.  After a couple tries it will finally go.  Part of my probably here is likely the plain 3750's that always boot faster and come up as the master.  I should manually set the master to one of the G's.  What I'm wondering is who else has 7-9 3750's stacked and are they performing well for SNMP, telnet, etc?  I've got another newer stack of 7 3750E's that I need to add one more switch to.  Need to decide if I want extended downtime to break the stack up or just add the 3750X to make member 8 and hope it performs well.  I have 50+ 3750 stacks working great on our campus.

Now I'm have IOS ver. 12.2(55)SE but from time to time I'm experiencing strange system freezing. It means that all systems connected to the stack are working very, very slow. It hapens ones, sometimes twice a month and takes 5 minutes. I didn't find anything strange in logs (neither on switch nor router). I would like to install other IOS version. Could you recomend me the most stable version for this stack (built from these different models) ?And the secound question:  - Is it possible to copy SE1 manualy to every switch and reload one by one manualy. Will they join the stack and work fine after reload or maybe there will be a IOS mismatch ?

Cisco Switching/Routing :: 3750 Stack Crossing Mandatory

i mean you can connect port 1 to port 1 on the other and connect their port 2 to each other

1- is it any benefit in the cross connection ?
2- do i encounter any problem if i stack a 24ts with a 48ts or a 12s-s (all are 3750)
3-i stacked two switches with each other and the ports became 1/0/* and 2/0/* and then i removed stack but on second switch the ports are still 2/0* !! when there is only one switch the interfaces should be 1/0/*
