I have 2 6500 Core switches in VSS configuration. Redundant VSL links are configured between them in below fashion.
Te1/5/4 of switch1 is connected to Te2/5/4 of switch2 in Portchannel1 which is up. Te1/5/5 of switch1 is connected to Te2/5/5 of switch2 in Portchannel2 which is down.
My "show interface Te5/5","show int status","sh int te1/5/5 transciever" show SPF is detected but the port is down at both Layer1 and 2 I see light coming from Rx and Tx of SPF modules and cables.
We have a current 3-stack 3750 ( 48-P,48-TS & 3750v2-48PS ) running fine. There is a plan to introduce a fourth stack member ( 3750X-48P ) into this stack.as per cisco documentation, it suggests to use 3750X as master for a mixed stack. In this case, we will need to upgrade current other 3 stack switches to a latest version.,Can we do a no-downtime ios upgrade on the existing 3-switch stack?, when this upgrade is done, is there any way to have the new ios pushed down to all three stack members at the same time or do we need to each member upgrade seperately?, for adding the fourth member, is it acceptable if master is ruuning ver eg. 12.2(55) and all rest of the members run ver 12.2(53) ? will this create any issues and will stacking be successful.
I have a switch stack with three WS-C3750X-48 switches running 12.2(55)SE. Recently, stack member 3 went offline for a few minutes, after being online for over a year. A show version on member 3 reports that the system returned to ROM by power-on.
Stack member 3 shares a UPS with a router that did not lose power and all three stack members have stack power with four 350 WATT power supplies between the three of them. There are no crashinfo files on any of the switches, log files show the stack ports on the other switches going offline then switch 3 being removed from the stack.
Surveillance recordings show there was no one near the switch during the time and AAA accounting shows no clues. Is it possible the switch crashed without leaving a trace in the logs, a crashinfo file and report that it returned to ROM by power-on?
I've read before that loose stack cables can cause stack member reboots. Would such an event generate log messages other than the stack ports changing states to down?
I have 2 3750-x members in a stack running 12.2(58)SE2. I am able to console into the stack master, which happens to be the top switch, but not able to console into the 2nd member. I get the screen stating the console is available but never get the prompt to login. Is this expected behavior?On our stacks of 3750v2's, I'm able to console to any switch in the stack?
Pure 3750X-48PS ip base stack.One switch reboots from a power issue (possibly the master switch? Haven't confirmed yet in the 3 cases I've seen)The rest of the stack stays running fine (as it should), the rebooted switch rejoins the stack just fine
What I've observed after this scenario takes place is that network throughput on any port in the entire stack is severely degraded. Prior to the one switch rebooting, I can hit gigabit transfer rates going anywhere on any of the switches in the stack. After one member reboots by itself, I typically hit a transfer wall around 5-20mbps in one direction and sometimes better going the other direction. I've only confirmed this on 3750X stacks and I can replicate it every time. Newest code I've experienced it with is 12.2(58)SE1. I have not seen confirmed reports of this on older 3750 (E, G, plain) stacks of which we have a ton of.
Rebooting the entire stack so that all 3750X members are coming up at the same time solves the transfer rate issue every time. I would think there has to be a better way to get performance back to normal or prevent the performance hit in the first place.
I have a 3 member CBS3120X-S stack in a HP C7000 enclosure (switches 1, 3, and 5). Switch 1, (the previous stack master) is not showing up in the stack and all the ports are down. Switch 3 has taken over as master, but I don't know what happened to switch 1. The system and stack lights are green and I am not seeing any messages in the log. I reset switch 1 and that did not resove the issue. I disconnected the stack cable and reset the switch again (pulled it out and pushed it back in) and connected to it with a console cable. I get nothing on the console, not even rommon mode. I was connected at the default baud rate that worked when I connected the conole of the other switches in the stack, so I don't think is a serial configuration issue. If this is CBS hardware problem, I don't understand why the system light is green.
I had a problem about authentication use AD group member. Below webiside is the way I config on ACS.
[URL]
I'm using ACS 5.1.0.44 and this version has a bug , ACS cannot read AD group. I have to add it manually . After I change the access policy from Internal user to AD1. I can use anyone AD ID to pass authenticaiton. I finished all config from the website had same result.
I checked the access polices -- default device admin -- authorization , the new rules I created had no hit count. How can I make sure that I make a right config ?
I have a customer buys 12 x WISM and build up a mobility, when I add the final WLC to mobility, it prompts that there mobility group has reached the max of mobility member, but the total member is 23, according the configuration guide, it should be allow to 24 member, do I hit some bug? My using version is 7.0.98.0.
I have two 3750X in a stack. Each 3750X has one 10Gb uplink to primary core1 and one 1Gb uplink to backup core2 configured in 2 etherchannel groups. The member switch has bad ports, so I need to replace it. I have spare 3750X unit. Is it possible to connect the spare unit to the stack and then move the RJ-45 cables from the member with bad ports to the new member? That way I can minimize servers downtime to just a few seconds..If that would work, then the last step would be to move the 10Gb networking module from old member to the new one, as well as the secondary PSU. Is it doable? Also according to the documentation, all I need to add new member is matching IOS version, correct?
i have server with two uplink to pair of 6500 non-VSS, this server member of vlan 100 sw-1 is active HSRP while sw2 is a standby HSRP , how can i make this server forward traffic on both Link . the server admin told me only one link is active (green) on the server while the other link is orange
We have a L3 gig link between 2 locations (6513 <-->4507). Each location got its own addressing scheme and vlan interfaces on the edge switches.For our new exchange servers, I received a requirement on having the possibility of single vlan at both locatons. so that the all the replicaton traffic between both location servers (Prod/DR). Ex: Create a new vlan at 6500 site with an addressing scheme 192.168.100.x and having the same addressing scheme vlan stretched over the L3 link to 4500. The link is not MPLS. I read few posts in the forum and seems it is possible if we have MPLS. OSPF is the routing protocol.
I've got a 3750 stack with a 3750-48p being switch 1 and a 3750-12s being switch 2 and switch 2 is the master. I would like to change the stack member numbers. I would like the 3750-12s to be switch 1 and the 3750-48p to be switch 2. I undertand I will have to reboot the stack for the change to take affect but here are my questions: How would this change affect the stack running-config ? will the switchport config follow the change ?
I have 2 controllers as below one with 6.0 version and other with 5.2 version AIR-WLC4404-100-K9 6.0.202.0 AIR-WLC4402-12-K9 5.2.178.0 GUEST..Control path between controller flaps.All mobility anchors on wlan index 7 are down.All mobility anchors on wlan index 3 are down.Control path to mobility member x.x.x.x is down.No problem observed when i have software 5.2.178.0 on both the controller.

I have pair of ASA 5550 and I am trying to copy a new config to my member1 (active) as the new configuration I want to use for the pair. I want to copy this to start-up config on member1 and then reload member1 and have it copy the same config to member2 (stdby). I guess I am trying to understand if I copy the configuration to member1 and reload it, member 2(stdby) will have become active and try to copy the old configuration to member1 which I do not want.
get the commands straight that I need to execute to make sure the new startup config gets to both members without being overwritten?
indicate why my ethernet ports are in suspended state for some reason, i need an indication why this may be and what i can do to fix this issue. configuration below. I have a 7010 which i'm using to connect to two 5510's. I have one vPC connecting the two 5510's to the 7010. I have a vPC domain configured between the 5510's. and no issues at all. My Nexus 7010 port channel members are suspended for some reason.
The stackwise marketing info states that when a failed member is replaced with a new switch the replacement switch "gets the exact configuration of the old device". I would figure it takes a little more than just disconnecting and connecting a new switch in the same spot on the stack. doing this with 3750 family switches? What are the steps to prepare the stack for a new member? what steps need to be taken on the replacement switch before insertion into the stack to make sure it gets configured like the unit it was replacing?
We have got 2 3750 switches in the stack which are connected to access switches with 2 uplink ports . each 1 uplink from each physical stack switch .
Due to some power issue our member switch got rebooted. After the reboot the access switches were not reachable through ping , but i was abe to see access switches in "show cdp neighbour" . Then i rebooted the master switch and member switch one after other . after which i was able to ping the access switches.
I just configure VPN for end users in PIX515e with IOS 8 and get stuck with "Tunnel Rejected: User (msveden) not member of group (VPN-shared), group-lock check failed.". tell me how I add user to my VPN group?
Four 6500 connected to each other to form a full mesh. Switches 4 and 7 is running eigrp. A question came up, why didnt it have eigrp on SW 2 & 3 ? Will it still be redundant if link between SW3 and SW4 is removed? If redundancy is working, SW3 should be able to find its way to SW4 via SW7 or SW2, yes?
Recently, the eigrp was configured to SW 2 and SW 3 as well, it included the “redistribute static” statement. The route for SW2 and SW3 now has the VLANs, 51 or so. Sent ping from a PC to VLAN1 IP of SW3, then link between SW3 and SW4 was disconnected, network connectivity went down for about 20secs, and ping came right back. Thought it was a success. All of a sudden, outside connectivity was lost. Ping within the LAN was successful, but no internet connection.
The eigrp on SW2 and SW3 was removed, and the internet connection came back up. The initial concern was that although there is physical redundancy in place, the other routes may not be known. Hence, eigrp configuration has been attempted for SW2 and SW3. Perhaps the “redistribute static” should have never been configured on SW2 and SW3, SW7 does not have the “redistribute static” statement anyway.
Without eigrp running on SW2 and SW3, does it still have redundancy? For what it’s worth, SW4 and SW7 are both VTP servers. With the current configs, does it still have redundancy? Link redundancy was never tested; it always has been assumed that it works. Later today, with it’s current config, the link redundancy will be tested.
I have two Cisco 6500 switches connected via fiber, this is my small network. One end goes to a provider, and the other end goes to a server. My IT department wants some sort of link state propagation since the provider keeps going down, but the IT team is unaware until they contact me.
We provide a Layer2 point-to-point circuit, access ports at the ends. We use V LAN's to transport the traffic. Please let me know if there is anything I could do to support link state propagation.
1) current switch have below mentioned switch stack details . switch#sh switchSwitch/Stack Mac Address : fcfb.xyz.8b80H/W CurrentSwitch# Role Mac Address Priority Version State----------------------------------------------------------*1 Master fcfb.xyz.8b80 10 0 Ready3 Member 2893.xyz.3180 1 0 Ready
2) I am in process of changing switch member number from 3 to 2 , I executed the command on the global config mode " switch 3 renumber 2 "but I yet to reload the switch .
here I have I doubt . as currently the ports module are fas 1/0/1-48 and fas 3/0/1-48 under respective vlan . once I reload the switch is the switch port module number will get change to fastethernt 3/0/1-48 to fastethenet 2/0/1-48 ??? . if it happens the vlan configuation which configured on the fas 3/0/1-48 module also get configured automatically or I need to configure manually
3) as i said i have execuated the command : "switch 3 renumber 2 " , how to remove this or revert the change , as i checked in the running config this command not exist .
switch ( config) # switch 3 renumber 2WARNING: Changing the switch number may result in aconfiguration change for that switch.The interface configuration associated with the old switchnumber will remain as a provisioned configuration.Do you want to continue?[confirm]Changing Switch Number 3 to Switch Number 2New Switch Number will be effective after next reboot
I have 2 pairs of Nexus 5000 units (pair 1 and pair 2). A pair consists of 2 Nexus 5000 (A and B) connected to each other via a VPC containing 2 ports ie P1-5KA -- P1-5KB (vpc domain 6) and P2-5KA -- P2-5KB (vpc domain 10) [code] Hsrp exists between all four with a virtual address of 10.18.136.1. P1-5KA is the Active with P1-5KB as Standby.
I can ping between the four using their SVI addresses. I am unable to ping the HSRP virtual address .1 from P2-5KA or P2-5KB.I can ping ok only if I shut the VPC between P2-5KA or P2-5KB or define another mac address under the HSRP config other than the system default. IP Packet debugs show that ping sourced from P2-5KB to P1-5KA loop between P2-5KA -- P2-5KB. Pings sourced from P2-5KA to P1-5KA are transmitted but none of the 4 device debugs show a receive. both peer-gateway and delay restore 120 have been configured under all vpc domains and all units rebooted.
I have a pair of 3750E-24PD-S stacked together, it seems after stacked together the stacked switch always flood the console screen with these messages which are not true: [code] Switch-2 is the stack member, Switch-1 is the stack master. The RPS fan failed refers to RPS2300 or the internal power supply of 3750E? Even when I turned on the RPS2300 the stacked switch still display the messages. Also I have two RPS2300 serving stack master and stack member respectively both RPS2300 were switched off why the messages only refer to Switch-2 and not Switch-1? [code]
I am trying to implement priority queuing (LLQ) on a pair of 10GE links between a 4507 with Sup6E and a 4948 which are configured as an etherchannel. I am unable to configure a priority queue on the 4507. I am running into the following issues:
I want to have a priority queue for voice traffic and specify minimum bandwidth for a critical application. If I configure a class with the priority command it will not let me use the bandwidth command on another class unless the priority class is policed. If I try it without the police command I get the message "bandwidth kbps/percent command cannot co-exist with strict priority in the same policy-map ". If I add a police statement to the priority class then I don't get this error.
When I try to apply the resulting service-policy to the physical interface it says "% A service-policy with non-queuing actions should be attached to the port-channel associated with this physical port" and does not add the command to the config.
If I try to associate the same policy-map to the port-channel rather than the physical interface it says "% A service-policy with queuing actions can be attached in output direction only on physical ports" and does not add the command to the config.
All of the other interfaces on the 4500 are working OK. The trunks have auto qos voip trust configured and access ports are marking the critical application traffic.
The 4507 is running 12.2(44)SG1 EnterpriseK9. I don't have the luxury to upgrade blindly to fix the problem unless I can identify a specific bug that is causing the problem.

We have got a big problem with our NAM (WS-SVC-NAM-1) - it does not boot. We have got a second one and in an other chassis. I changed the chassis, and RAM and Flash from the other one. RAM and Flash are ok.
We checked the disc (hardware) with an Ontrack-tool -it is OK.
