I've got a 3750X, IOS 15.0 IP Base license, reset to factory defaults, and I want to use the FastEthernet0 out-of-band management port on the backside next to the console port. The idea is that this port should provide a management interface that does not participate in the routing table. Problem is, contrary to the documentation, that configuring an IP address on the interface does make it show up in 'show ip route'. So it's still part of the routing table. Also, I'm unable to find the commands to change this and set a default gateway for just the management interface. I'm pretty sure this has to be possible, I remember seeing something similar on an ASA once. The 3750 configuration guide on Cisco.com does not seem to mention it.I considered using VRF but it's an IP Base license, no VRF.
What is the point of it? It is not a remote console. If i reboot the switch i cannot get back to the out of band management port unless the switch is fully running. Is this only for security purposees? so all telnet/ssh is from an Out of band network?
regarding to the out of band Management interface , if I configured an intervace vlan to be as a managment interface for one vdc ( the default vdc ), when I connected to this vdc via telnet , can I switch to any other vdc ? ( suppose that I have the Admin role which allows me to enter and config all the vdc's )If that is possible so that I dont have to make a dedicated managment ip for each VDC I need to do that only if I want to make vdc admin's account to allow some users to access specific vlans only , is that true ?
i have a stack of 3750x, with minimal configuration. there are two vlans, and two vlan interfaces with IP addresses. when i ping out from this switch to another host, it picks vlan1's ip address as the source automatically. i tested this by doing two pings with extended options using each vlan's interface as the source, and got different results. how the switch decided to use the first vlan's ip address as a source.
I have created a management vlan on my network of 2950 and 3750 switches. One 3750 has a trunk to each of the 2950 switches which includes the management VLAN. On that 3750 the vlan and line protocol are both up even though there is no specific port assigned to the vlan; I believe the trunk connections allow the vlan line protocol to come up. On another 3750 stack I have my VLAN defined with no ports designated or trunks; the VLAN is up however the line protocol is down.
I have a stack of 3750-X that are used to both switch traffic inside V LAN and also to route a couple of WAN ranges from our up link provider to the DMZ v LAN.Now I'd like to have a SVI Vlan1 with an IP in the "management v LAN", but I'd like that SVI not to be rout able.
More exactly :
- no traffic should ever exit that interface that's not the generated by the router itself (ssh/snmp/...) - no incoming traffic on that interface should be forwarded anywhere - I'd also like to have a different default gw to be used by traffic generated by the switch itself. (for eg, ssh traffic coming from any another sub net like 10.2.0.0/24 to the switch SVI Vlan1 ip 10.1.0.1/24 should be routed back through the Vlan1 gw and not through out up link ptp gateway)
I think I can achieve the first two with ACLs on the SVI. But not sure about the last one ...
i have: two nexus 5596 connected each other the mgmt0 is NOT in use SVI for keepalives with IP address and /30 netmask vpc-keepalives running over fiber in e1/1. this works well uplinks to datacenter distribution switch (Cat 6500 VSS) over fiber on port-channel 1 (e1/2 and e1/10), also carrying the management VLAN (vlan 14). SVI with an IP address for management purposes
I can't get this to work. i can ping my whole network from the nexus, but not the nexus from my network. also pinging inside the mgmt vlan is not possible.
I'm trying to get an IP_ADDR set on the management port in SWITCH: mode but for some reason the port seems disabled. PC shows connection unplugged. MGMT_INIT is not a valid command (not listed under '?' ). Bootloader version is 12.2(53R)SE2 FC1.
I got question about Cisco SF300-24P- is it possible to have management vlan in other vlan than in default vlan?I have default vlan 10 and voice vlan 20, I need to reach switch through voice vlan so I need to set up, interface vlan 20 with ip address. I ask these, because in gui, under Management Interface, IPv4 interface,under Management VLAN, I can only choose vlan 10, which is my default vlan, I dont have option to set ,up, in this case, vlan 20 as management vlan.
In mucking around with my 4500 I accidently deleted the ip address that I use to get into it with telnet and CNA. I have a console cable hooked up to and I'm in that way but the commands I got off the internet did not work. Those commands were set interface sc0 10.x.x.x/xx and set interface me1 10.x.x.x/xx. It didn't like interface and I notices when I did a set ?
I'm trying to figure out how to (or if I can) setup the management interfaces (fa1) on a couple of new 4500X switches. My issue is that the 4500X's themselves are the gateway for my management VLAN (.1 HSRP virtual, .2 and .3 SVIs on the pair of switches).
I would like to assign addresses from the management VLAN to the router Fa1 management interfaces but the software configuration guide seems to note this is not supported (and indeed it doesn't seem to work).
Physically I have Fa1 from core-1 into a port on an adjacent switch. Fa1 from core-2 also goes into a port on that adjacent switch. Both are in my management VLAN, whose SVIs are on the cores themselves.
In change network topology, we are going to assign PC's Gateway as Switch (3750X) IP Address rather than server IP Address. Currently we have configured all Sytems's Gateway is Internet Server IP Address which we are going to replace with Switch IP as Gateway.Issue is while connecting specific application like team viewer in which application tried to send keepalive message to the live server and in case of switch/router IP as gateway. Connection doesn't established. However it is working fine when Internet Server IP treated as gateway.
i joined because i keep on having the same problem. i read around the forum a bit before joining and i saw that mcafee was causing the problem for a lot of people. i dont have mcafee so that cant be it several crashes per day. like, literally close to 100 of them.
Periodically, I drop internet everywhere around my college's campus. I'm literally four feet from a router, but it doesn't seem to matter. I'll disconnect, run troubleshooter, and I'll get the error message saying that the default gateway is not available. My college is designed for Macs, but I'm running Windows 7. My Mac colleagues do not experience problems. The computer works at home and at nearly every other wireless network I've brought it in range of. Specifically, either IBM or Dell.

I recently got a new laptop and ever since, the internet goes in and out. Most of the time it is not out long enough to display the no connectivity icon or stop music from streaming but it is noticeable. When I run the troubleshooter it says that the default gateway is unavailable. I tried manually setting the connection information but the same thing keeps happening except the troubleshooter then says that DHCP is not enabled. I've disabled every firewall I can find and updated all the drivers available. Here is my info:[CODE]

I am trying to get rid of 2 old 2651xm's and 2 2950's from my CCNA days and want to get into the ASA realm. Can I be able to use the ASA, not only as a security appliance / firewall, but also be able to write the access lists, etc, to be able to use this as my router to push packets to and from my internal LAN to the outside world? I guess I should have stated as this being the front end device to my network, just after my DSL Cable modem, that is..and being the only device. I am trying to have this as my main router /firewall solution and then I have an old Linksys router I will pipe off one of the L2 ports to have an AP for my wireless devices? Is this a real solution an ASA can provide?
i'm having problem to ping succesfully default gateway on Router1 from Router2. Basically i can: - ping from R1 the serial interface on R2 and default gateway on R2 - telnet from R1 to R2 - ping from R2 to serial link on R1, BUT I CANNOT ping default gateway from R2 to R1 Below is the photo showing topology and running configuration on both routers
We have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?
When I plug my laptop up to our modem, all i get is local access. IPconfig gives me to default gateway or dns suffix. Naturally there is no wireless. My roomates laptop runs fine wired or not and we have the same set up.Not sure what to do.
I am having issues playing certain games on my ps3. So I've been searching for solutions and I came across a video that wanted me to go to run/cmd/ipconfig. I have little knowledge of computers but I'm not sure that what my ipconfig is showing is supposed to be there. At first I googled and learned about ipv6 addresses because i found that weird but i think that checks out fine. I then googled about the weird numbers and letters in my default gateway and came up empty. Is there a reason thats there?
I have Squid proxy installed on a ubuntu box here. Currently all my PC's use my ADSL modem as their default gateway but what i wanted to do was see if it was possible to use the ubuntu box as the default gateway, and have it route through Squid to my ADSL modem.
I am trying to change the password on my D-Link router. So i typed ipconfig into cmd and the default gateway i get is 169.234.95.I have tried what used to work at home such as 192.168.0.1 and all of those.
I have a VM server, whose IP is in customer VLAN600 ( 172.60.60.10/24 ) and Peer end is switch then Firewall.Switch is configured with same VLAN600 and learning mac-address of Server on VLAN 600, Firewall is also having VLAN600 and IP is 172.60.60.1/24.Server is not able to Ping/reach Firewall and vice versa.
Basically, I'm using a broadband modem, which appears to be connecting fine, with all the required lights being on. My ISP says that, from their end, everything is perfect. Even my laptop shows Local Area Network as connected.However, for some reason, I am not able to access the internet. I was able to use it till last evening, but suddenly the internet stopped working. On Google Chrome, it says that there is no DNS or something.Subsequently, when I tried to access my modem settings, it shows as 'webpage not available'. I then noticed that there is no default gateway! I was able to access it the day before, but now I can't.
i recently had to do a 30/30/30 reset to my Linksys WRT150N which has DD-WRT installed on it... I can't access the configuration settings on the router by typing in 192.168.1.1. I did IPCONFIG/ALL and couldn't nothing came up for Default Gateway.
It only happens with 1of my laptops, all others have not problems. In the network and sharing ctr, it intermittently says Access type: internet then suddenly I get a no internet access. I've tried release renew DNS, reboot computer, release/renew IP. When it says I have internet access, I attempt to connect to no avail.
I'm really not clear about default-gateway on switch command, not the function but how its works.i have 1 multilayer switch (MLS 1) that have 2 vlan within it, vlan 2 and 100. on vlan 2 i assign ip address of 192.168.1.1 and on vlan 100 is 172.16.1.254. both vlans are up. then under that multilayer switch i added 2 more MLS (MLS 2 and MLS 3), and the links of MLS 2 and 3 to MLS 1 are trunking. and both MLS 2 and 3 have a same vlan with MLS 1. that i assign an ip address on vlan 2 in MLS 2 192.168.1.2 and i set default gateway 192.168.1.1, and i do the same to MLS 3 but the ip address of vlan 2 is 192.168.1.3i already setup the routing protocol on MLS 1 so that vlan 2 could contact vlan 100. but the fact it doesnt work at all, both MLS 2 and 3 cannot contact vlan 100 eventhough that are already have default-gateway setup, is there anything wrong with the configuration ??
Why it makes problems to use a default route on a BGP-router (cisco 6500 with sup720 3bxl).Only a very few amount of hosts have that kind of problem and the 50% paket loss is only between this hosts. So another host has no loss to any of the affected hosts. looks for me like there is a problem in the CEF-table.The router has a BGP-fulltable. The gateway of last resort is only set for cases like a flapping BGP-route, so that the traffic is sent to a default next hop, because sometimes he knows a better route which isnt flapping.
