Questions & Answers
What is the MEM-LC1-PKT-256 line card buffer memory?
The MEM-LC1-PKT-256 is a high-performance buffer memory module providing 128 MB for transmission and 128 MB for reception on compatible network line cards.
Which devices are compatible with MEM-LC1-PKT-256?
MEM-LC1-PKT-256 is compatible with Cisco® 4000 and 5000 series modular routers that support 128 MB/128 MB line card buffers.
How does MEM-LC1-PKT-256 improve network performance?
By increasing packet buffering capacity, MEM-LC1-PKT-256 minimizes packet loss and latency during traffic bursts, resulting in smoother throughput and higher QoS.
Is MEM-LC1-PKT-256 hot-swappable?
Yes. When used in a chassis that supports hot-swap, MEM-LC1-PKT-256 can be installed or removed without powering down the system.
How do I install the MEM-LC1-PKT-256 module?
Power off the chassis (if not hot-swappable), remove the existing line card, insert the MEM-LC1-PKT-256 module into the slot, secure it with screws, then power on or reset the device.
Do I need a firmware update for MEM-LC1-PKT-256?
No firmware update is required; the MEM-LC1-PKT-256 module is plug-and-play with supported IOS and IOS-XE releases.
How can I verify the MEM-LC1-PKT-256 installation?
Use the CLI command “show platform hardware packet-buffer statistics” to confirm that 128 MB Tx and 128 MB Rx buffers are recognized and operational.
What environmental conditions does MEM-LC1-PKT-256 support?
The module operates reliably in temperatures from 0 °C to 40 °C and relative humidity between 5% and 85% non-condensing.
