Duplicate/incorrect MAC addresses in the CAM table

I am doing SNMP queries of a Cajun P333 switch with Avaya IP phones connected to it, specifically to associate the phones' MAC addresses with switch ports. The problem is that if, for example, 2 phones trade switch ports, both MAC addresses will show up on each port - the old MAC address is not removed. Is there some sort of ARP timeout or something that can be adjusted? Thanks in advance,

Re: Duplicate/incorrect MAC addresses in the CAM table

This is from the Cajun P333R manual but it should be very similar if not identical.

Good Luck.

arp timeout Command
Use the arp timeout command to configure the amount of time that an entry
remains in the ARP cache. To restore the default value, 14400, use the no form of
this command.
The syntax for this command is: arp timeout <seconds>
The syntax for the no form of this command is: no arp timeout <seconds>
To set the arp timeout to one hour:
Router(configure)# arp timeout 3600
To restore the default arp timeout:
Router(configure)# no arp timeout
ip-address IP address, in dotted decimal format, of the station
hardware-address 48-bit address of the local data link
seconds The amount of time, in seconds, that an entry
remains in the arp cache.

How to stop user privately setting up a static IP address?

Huawei S2300/3300/5300 series switch although no H3C switches am user-bind command, but through the DHCP Snooping function can also be realized IP+MAC+ port binding to prevent users set up a static IP address. For example, if the request port Ethernet0/0/1 in addition to the static IP address for the, MAC address for the 001c-2309-9aa7 corresponding to the user, all other static IP users can not access the internet. Configuration is as follows:
Configure the device DHCP Snooping
# enable the global DHCP Snooping function.
[Quidway] DHCP snooping enable
# configure user side interface of VLAN.
[Quidway] VLAN 100
[Quidway-vlan100] quit
[Quidway] interface Ethernet 0/0/1
[Quidway-Ethernet0/0/1] port default VLAN 100
[Quidway-Ethernet0/0/1] quit
# enable VLAN DHCP Snooping function.
[Quidway] VLAN 100
[Quidway-vlan100] DHCP snooping enable
# configuration interface for packet inspection at the user side
[Quidway] interface Ethernet 0/0/1
[Quidway-Ethernet0/0/1] DHCP snooping check ARP enable
[Quidway-Ethernet0/0/1] DHCP snooping check IP enable
[Quidway-Ethernet0/0/1] quit
# configuration static binding table entry
[Quidway] VLAN 100
[Quidway-vlan100] DHCP snooping bind-table static IP-address mac-address 001c-2309-9aa7 interface Ethernet 0/0/1

How do i split out multiple static ip's

You need to attach a DHCP-server to the hub/switch, and configure that DHCP-server to "reserve" a specific IP-address for the MAC-address for the network adapter inside each of the computers that is to receive a "static" IP-address.
For a DHCP-server, you can connect a "cross-over" Ethernet cable from one of the switch-ports to one of the LAN-ports on any "home" wired router. That "home/SOHO" router will become the DHCP-server for all the computers connected to the switch.

Which model are you talking about ? I have included both

Here is the OSI model
Layer 1 = physical medium & signal on the wire (physical)
Layer 2 = MAC Address and SNAP (ATM) (data link)
Layer 3 = IP Addressing V4 V6 (network)
Layer 4 = TCP/UDP (RTP, RTSP) (transport)
Layer 5 = Duplexing Half or full (Session)
Layer 6 = HTTP, FTP, SNMP (presentation)
Layer 7 = Web browser, FTP Client, (application)

TCP Model:
Layer 1 = physical medium & signal on the wire (physical) (Hub and reapeter)

Layer 2 = MAC Address and SNAP (ATM) (data) (Switches and bridges)

Layer 3 = IP Addressing V4 V6,
Layer 4 = TCP/UDP (RTP, RTSP) (Internetwork) (Firewall, IPSEC) Routers

(This function is split between 4&5) Duplexing Half or full

Layer 5 = , HTTP, FTP, SNMP, Web browser, FTP Client, (application) (programs)

I hope this helps,

Thank you,

Just connected to cable modem from dsl

two things are you hooked up from the dsl to the router via Ethernet or usb is so check the settings in the router, it should be auto, so it could choose but lets not assume anything.may sure dhcp client or server is enabled on the router, if not it would not pick up the ip adddress from dsl.
Is the mac address of your computer hardcoded to your dsl, if it is then you would have to clone your pc mac to the router for it to work.
If this is not the case, try a different router if it works the router is faulty. if that does not work plug the dsl directly to the pc and go to start, run type ipconfig /all if you recieve an ip address and you can see a dns address from your isp and you can go to the internet, then the problem is your router, if not the problem is with you isp dsl, please contact them. was this helpful let me know.

How can I reset it back to original configration

Hey Eric, I do use same Avaya switch at my lab at office. To me what you have to do is quite simple, first of all you have to get from your network administrator the following info: - Free IP to assign to the switch - Subnet - Gateway (If you ping such IP from a machine of same subnet, there will not be an answer). Then log as superuser (#) and do this: 1. Type set interface inband Replacing , and with the VLAN, IP address and netmask provided by your network administrator and press Enter. (for VLAN you can list them and decide which one to use, but normally you should use 1) 2. Type reset and press Enter to reset the stack. 3. After the Reset, perform login again as superuser.  4. Type set ip route , replacing and with the destination and gateway IP addresses. (If you want all packets not from your subnet to be send to the gateway, then use as destination, list routes set on device for more info) 5. Press Enter to save the destination and gateway IP addresses. That's all. Your switch will be rechable from your same subnet and from other networks if your gateway is working properly and there's no other element blocking you the access. Good Luck!
